Yes, thank you.  I was fiddling before I got your post and I came up
with roughly the same.

preg_match_all('|{(\$[^}]+)}(.+){(/\1)}|Us', $out, $matches);

Shawn,

First thing I see--your first capture group doesn't include the $, and
so your final capture group will always fail given your current $out
(because it's looking for {/sites} instead of {/$sites}). Also, your
{} are outside of your capture group in \1, but inside in \3. Here's
what I came up with:

$out = '
{$sites}

   
   {Site.id}
   

{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);

Produces this:

Array
(
[0] => Array
(
[0] => {$sites}

   
   {Site.id}
   

{/$sites}
)

[1] => Array
(
[0] => $sites
)

[2] => Array
(
[0] =>

   
   {Site.id}
   


)

[3] => Array
(
[0] => /$sites
)

)

Keep in mind, I had to view the page source in order to see the HTML
tags, but it showed me everything I expected to see.

http://www.regular-expressions.info ... that's how I learned. :)
Anyway... your match might be something like:

^/([^/\.]+)/?$

And the rewrite...

"/p.php?purl=$1"

To break it down, the match is looking for "The beginning of the line,
followed by a forward slash, followed by (begin capture group) 1 or more
characters that are not a forward slash or a period (end capture group)
followed by an optional forward slash, followed by the end of the line."

The rewrite is fairly straightforward.

I went 100% generic with the match due to your following e-mail that
stated "jasonpruim112" could be any username. If "112" is necessary for
the match, it would be more like:

^/([^/\.]+112)/?$

Hope this helps,

That's what I was doing.  I was parsing A:HREF, IMG:SRC, etc.

Go to http://www.enetwizard.ws and it might make more sense.

All the links on the left have an ONCLICK=location.href = ''

the TR tag.

This solution allowed me to make sure those links included the  
session

information, just like the A:HREF links do.

It also had the advantage of updating the links in my CSS.


O that breaks accessibility standards! Compliment the  
'onclick's with

onkeydown at least :)

But still you get a solid onclick=... scenario

If these are visible in the source then they are fairly easy to  
pick out


Though you may need more than 1 regex ;)

My complaint here is, don't break accessibility :)



And don't forget the folks who have javascript turned off or are

If we are talking clickable links, why not focus on the  construct
itself? Otherwise URLs are just part of the page's textual content... Very
difficult to parse that

Disseminating an  tag isn't brain-meltingly difficult with a regex if you

In my opinion, it is the most reasonable solution.  I have looked all over
the web for something else, but this works perfectly for me.  It's
impossible to tell where an url starts and ends if you don't have it in
quotes or single quotes.  If someone really needs to find all the urls in a
page, then they'll code their pages to make use of this limitation.

Nope.

:-)

I got WAY past 20 year mark before I even began to pretend to
understand the minimal amount of regex I can do now.

Most things complicated enough to need regex are too complicated to do
with regex, if you know what I mean...

There's a very narrow "band" of problems where I'm comfy with regex,
really.

Anything simpler than that is just a substr or explode.

Anything more complicated, and I just don't want to try to maintain
the mess of not-quite-random characters needed to make a so-called
"pattern" and I'll find some other way to break the problem down into
sub-problems.

Those sub-problems might then be amenable to a reasonable regex, of
course, but I'm just not gonna tackle it in one big messy pattern.

And it's missing the original requirement of matching https URLs, so
maybe make it be ...https?://...

Plus, http could be IN CAPS, so change the U to iU

And, actually, SOME old-school HTML pages will have neither ' nor "
around the URL, and are (or were) valid:
href=page2.html
was considered valid for HTML for a long long long time
So toss in (\"|')?
And then you may be finding URLs that are not actually linked but are
part of the "visible" content, so maybe you only want the ones that
have
]href=
in front of them.

If I can toss off 3 problems without even trying...

So I still think Google or searching the archives (as I suggested
off-list) will be the quickest route to a CORRECT answer, but here we
are again in this same thread we've been in every month or so for the
better part of a decade...

PS the (\"|') bit may "move" the URLs into $matches[2] instead of
$matches[1] or whatever.

I'd roll those two into one expression:

RE: [PHP] Regex Help for URL's [ANSWER]

[Robert Samuel White]

In case any one is looking for a solution to a similar problem as me, here
is the answer.  I used the code from my original post as my guiding light,
and with some experimentation, I figured it out.

To get any URL, regardless of where it is located, use this:

preg_match_all("#\'http://(.*)\'#U", $content, $matches);

This match anything similar to:

'http://www.domain.com/dir/dir/file.txt?query=blah'

This is useful, if for example, you have a tag like this one:

http://www.domain.com/dir/dir/file.txt?query=blah';">

Now, for tags which are in quotes, rather than single quotes, just use:

preg_match_all("#\"http://(.*)\"#U", $content, $matches);


This is really only the first step.

In order to be useful, you need a way to process these urls according to
your own specific needs:

preg_match_all("#\'http://(.*)\'#U", $content, $matches);

$content = preg_replace("#\'http://(.*)\'#U", '###URL###', $content);

This will modify the $content variable to change all urls to ###URL###

You can then go through them one at a time to process them:

for ($count = 0; $count < count($matches[1]); $count++)

Bearing in mind that none of the replies (particularly that of Jochem, one
of the posters that should be held in high regard) have been rude in any way
at all, I understand your plight with regex's

You might want to try the Regex Coach... It allows you to test your regex's

I wasn't being rude. Although even If I was commanding me stop is rather
futile no? if I was being rude I would have said something like:

"read http://php.net/preg_match and find the get_links() function
 posted by 'max99x [at] gmail [dot] com'  you f*** wit"

now that would have been rude.

the argument that the length of time spent programming automatically
makes you 'not a slacker' is unbased. one does not equate the other.
personally I would assume anyone who had been programming for 20 yrs
would have a reasonable understanding of regexps.

RE: [PHP] Regex Help for URL's

[Robert Samuel White]

I am trying to get all of the urls in a web document, so that I can append
information to the urls when needed (when the url points to a domain that
resides on my server).  It allows me to pass session information across the
domains of my network.  Currently, I use a class I wrote to handle this, but
it only works when it finds the urls in a standard html tag.  I need to
expand upon this, so that it also finds urls that are in onclick events, for
example.  Here is a sample page from my website:


if (parent != self) top.location.href =
location.href;

Perhaps a tad rude, but I got a treasure trove of hits from Google in my
first shot:

   
http://www.google.ca/search?hl=en&q=regex+extract+urls+from+content&btnG=Google+Search&meta=

Formulating a good search query is a great skill to hone.

The biggest problem with trying to match a string with regex is you
have to know the definition of what the string can be, for example
can the data be:
  
   102-90 E 42  X 42 X 70 3/8
   102-90 E 42 X  42 X 70 3/8
   102-90 E 42X42X70 3/8
   102-90 E 42\tX\t  42 \t X\n 70\r\n 3/8

> 
> I have:
> 102-90 E [!MATCH!] [!MATCH!] 70 3/8

If you want to just match those two numbers then:

  /\s+(\d{1,2})\s+(X|x)\s+(\d{1,2})\s+(X|x)\s+/

If this is the case, where does the 102-90 E come from? This sounds
more like a data normalization issue than anything.

Eric, thanks for replying. I couldn't quite get that to work. Albert,
I'm currently working with what you suggested, though the unit names

$vals = preg_split(' ?X? ',$unit[1]);
echo "".$unit[1]."\n";
echo "Panel: ".$vals[0]."Width: ".$vals[1]."Height:

202-90B 48 X 48 X 69 1/4

If this string is always in this format 

 E  X  X 

then you could try something like:

// Very much untested
$unit = '102-90 E 42 X 42 X 70 3/8';
$split1 = explode('E', $unit);
list($panel, $width, $height) = explode('X', $split1[1]);

Do you have that expression embedded in single or double quotes? Please
show us the actual context.

Hi Pablo,

At a (reasonable) guess, I'd say it's because you're not using the "s"
pattern modifier in your preg_match_all()? The "s" modifier forces your
regular expression to match new lines with the "." metacharacter.

Try:

preg_match_all("/(.*?)/s", $str,
$out);

http://php.planetmirror.com/manual/en/reference.pcre.pattern.modifiers.php

Hope this helps.

Much warmth,

Murray

Re: [PHP] Regex Help

Hi, folks.   I'm having trouble with a simple regex.  I'm sure it's just
something small that I'm missing but nothing I'm trying is working.

In an HTML file I have comments like this:


various html crap here


Here's the regex I'm using:

/(.*?)/

And then the call to preg_match_all():

preg_match_all($printable_reg, $str, $out);

It's been quite a while since I've worked with regular expressions so
I'm not sure what the problem is.  The regex isn't throwing errors, it's
just not matching the content located between the start print and end
print comments.

Can anyone lend a hand or give some advice?


I'm thinking that perhaps you want to add the "s" modifier to your 
pattern...



From http://us2.php.net/manual/en/reference.pcre.pattern.modifiers.php


s (PCRE_DOTALL)

If this modifier is set, a dot metacharacter in the pattern matches 
all characters, including newlines. Without it, newlines are excluded. 
This modifier is equivalent to Perl's /s modifier. A negative class such 
as [^a] always matches a newline character, independent of the setting of 
this modifier.

You're not going to get far with that. Lots of people make 'funny' You
Wrote lines, and not all of them start with 'On' or contain the word
'wr[o|i]te'. You might be better off just searching for any sentance
that contains an @ sign, because they are very seldom used outside of
email addresses nowadays. And that doesn't make any promises, either,
because sometimes the whole email address isn't in the line, just the
person's name.

Ok, it's not the regexp for detecting email addresses what I need,
that's widely published, thanks. I'm using ereg to match this regular
expression:

(On)[\s\w\d\W\S\D\n]*(wr[i|o]te[s]?:)

That will match phrases like
"On 8/3/05, Carol Swinehart <[EMAIL PROTECTED]> wrote:"
the type "On date, name  wrote or writes:"

The thing is I tried this regexp with Regex Coach and it matches fine,
but ereg returns no match

ereg($regexpstr, $str, $regs)

I know there are some comments at php.net about how ereg has some bugs,
any idea if this could be one?

You don't escape hyphens like that in a character class. Put it at the
end of the list of characters like this:

[a-zA-Z0-9'-]

Then it'll match your test address. 

If you're trying to find out why a regexp isn't working, try
simplifying your test cases until it works. For example:

$email = "[EMAIL PROTECTED]"; // doesn't work
$email = "[EMAIL PROTECTED]";  // doesn't work
$email = "[EMAIL PROTECTED]";   // doesn't work
$email = "[EMAIL PROTECTED]";   // works!

I don't suppose this is the place for a rant about the futility of
checking email addresses with a regexp?

Re: [PHP] Regex help

[Philip Hallstrom]

I am currently creating a once off text parser for a rather large
document that i need to strip out bits of information on certain
lines.

The line looks something like :


"Adress line here, postcode, country Tel: +27 112233665 Fax: 221145221
Website: http://www.urlhere.com E-Mail: [EMAIL PROTECTED] TAGINCAPS: CAPS
RESPONSE Tag2: blah"

I need to retreive the text after each marker i.e Tel: Fax: E-Email:
TAGINCAPS: ...

I have the following regex /Tel:\s*(.[^A-z:]+)/ and
/Fax:\s*(.[^A-z:]+)/ all these work as expected and stop just before
the next Tag. However I run into hassels  around the TAGINCAPS as the
response after it is all in caps and i cant get the Regex to stop just
before the next tag: which may be either all caps or lowercase.

I cant seem to find the regex that will retreive all chartures just
before a word with a :  regalrdless of case.

I have played around with the regex coach but still seem to be comming
up short so i thought i would see if anybody can see anything i might
have missed.


Any reason you can't match everything from TAGINCAPS through the end of 
the line, then once you have that stored in a string, split it on ":"'s to 
extract the pieces you want?  Even elements would be the tag, odd would be 
the value...


just a thought.

To do it in one fell swoop you need to use lookahead assertions -- 
something like this:

if (preg_match('/(?=.*[A-Z])(?=.*[0-9]).{7,}/', $text))
echo 'Valid!';

I believe this matches for any string that has at least one uppercase 
letter and one digit and is at least 7 characters long.  However it 
allows other characters as well (not just A-Z and 0-9).  Lots of 
possible variations there.

I wanted to create a regex that force a PHP form text field to meet the

a. Must contain an 1 uppercase letter. [A-Z]
b. Must contain 1 digit. [0-9]
c. Must be a minimum of 7 characters in length. {7}
if ( ereg("[A-Z0-9]", $field) && strlen($field) >= 7 ) {

nope, a username like "1234567" would go trough ok. Which isn't what he

that's what I get for thinking too fast :)
Seems like you should be able to do then um... "([A-Z]|[0-9])" as your 
regexp (check on escaping the ()'s or not.  I can never remember)

Thanks, Michael! I guess it is time for me to go review those zero-width 
negative look-ahead assertions - don't know how I missed them ;)

And no, not an exam - this is real life. My days as a frolicking schoolboy

Thanks...I actually just realized that the parentheses around the first
ampersand are unnecessary (that was a leftover from a previous attempt), so
this is simpler and will work just as well:

/^(?:&(?!&)|[^&]){1,5}$/

Or if you don't care about capturing portions of the match and then throwing
them away:

/^(&(?!&)|[^&]){1,5}$/

Yup, use this perl regex:

/^(?:(&)(?!&)|[^&]){1,5}$/

Where 5 above is the maximum length of the string.  You can change this to
any positive value and the regex will still work.  Basically it says "look
for 1 to 5 single characters where each either isn't an ampersand, or IS an
ampersand but isn't immediately followed by an ampersand".  The (?!&) is a
zero-width negative look-ahead assertion which is like other assertions such
as "\b" that don't eat up the portions of the string that they match.

Sample code, tested:

$maxLen = 5;

$testStrings = array(
  'a',
  '&g',
  'd&f',
  'adfdf',
  'adfsdfff',
  '&f&f&',
  '&&dfds&',
  'dsdf&',
  'd&&df',
  'dff&&'
);

foreach ($testStrings as $string) {
  if (preg_match("/^(?:(&)(?!&)|[^&]){1,$maxLen}$/", $string)) {
print "$string matches.\n";
  } else {
print "$string does not match.\n";
  }
}

Hope this helps you (pass your exam? ;) )

No offense taken. The design isn't mine, I am "plugging in" to another 
system that expects a regex.

It is pretty easy to do with two regexps, one to check the length and 
another to see if there is a double &.  Would that work?  I don't know 
off hand how to do it with a single regexp.

If the design requires that every possible condition be checked with a 
single regexp then I would say, no offense intended, that the design is 
faulty.  Regexps are good tools but are not universal for all possible 
conditions one might want to test.

Gr.

Okay, how about that regex callback thingie thing thing, and you can use a
function that pretty much does: (strlen($1) < 42 && !strstr($1, '&&'))

$text = $_REQUEST['text'];

This is an example of something that is easier to do (and probably

if ((strlen($str) <= $maxlen) && (strstr($str, '&&') === FALSE))

interesting.  I usually try to specifically describe in english what I
am looking for.  in your case, I would say a string that begins with <
followed by zero or more spaces followed by a b or a B followed by zero
or more spaces followed by zero or more anything followed by >

/<\s*[bB]\s*.*>/ 

or perhaps it is enough to say match a < followed by 0 or more spaces
followed by a b or a B and not followed by a r or a R and followed by
zero or more anything followed by >

/<\s*[bB][^rR].*>/

These are untested but should be close and can be used in preg*
functions.  the greedy matching might grab too much stuff and I always
forget how to do that when I hit it.

try them, let us see the results and we can get there

I think something not unlike:

'/|>)/'

The point being that you either have JUST '>'  OR you have a SPACE and
whatever and '>'

I leave the capitalization and 'greedy' settings up to you.

The previous solution using ' tag where X is a single character in
the alphabet.

There's a pretty cool Windows/Linux product a colleague swears by that's
called RegexCoach (?) which will not only let you try out
expressions/values and tell you which ones pass/fail, but you can
highlight sub-sections of the expression/values and see what it matches
piece by piece.

It's donationware -- try it out and donate the $20 (oooh, hurt me) if you
like it.

Quick-n-dirty:

  preg_match_all('/(|)/iU', $doo, $match);

Feel free to extend to check for closing tags :)

Just off the top of my head (and untested!), I'd try something like

  /]*)?>/

Put in a \b to match a wordbreak after the 'b'. Something like this maybe:

  /]*>/i
.

okay, you didn't show the regexp you currently have no worries - I 
happen to have struck the same problem about 9 months ago when I had to 
screenscrape product info from a static site for importation into a DB,
heres a list of regexps which will hopefully give you enough info to
do what you want (the fifth regexp is the one you should look at most 
closely):

// strip out top and bottom
$str = preg_replace('/<[\/]?html>/is','',$str);
// strip out body tags
$str = preg_replace('/<[\/]?body[^>]*>/is','',$str);
// strip out head
$str = preg_replace('/.*<[\/]head>/Uis','',$str);
// strip out non product images
$str = 
preg_replace('/]*(nieuw|new|euro)\.gif[^>]*\/?>/Uis','',$str);
// strip out font, div, span, p, b
$str = preg_replace('/<[\/]?(font|div|span|p|b[^r])[^>]*>/Uis','',$str);
// table, td, tr attributes
$str = preg_replace('/<(table|td|tr)[^>]*>/Uis','<$1>',$str);
// strip out the first table and hr?
$str = preg_replace('/.*/Uis','',$str, 1);
// strip table, td, tr
$str = preg_replace('/<[\/]?(table|td|tr|h5)>/Ui','',$str);
// strip out all new lines
$str = str_replace("\n", '', $str);
// strip out tabs
$str = preg_replace('/[\011]+/', ' ', $str);
// strip out extra white space
$str = preg_replace('/[  ]+/', ' ', $str);

Simple:

while (preg_match("/()(.*)()(.*)(<\/h\d>)/is", $str)) {
$str = preg_replace("/()(.*)()(.*)(<\/h\d>)/is",
"$1$2$4$5", $str);

$str = preg_replace("/()(.*)(<\/h\d>)/is", "$2", $str);


Recommended:

$str = preg_replace("/(]*)(>)(.*)(<\/h\d>)/eis", "remove_br('$4')", $str);
function remove_br($str){
return preg_replace("/(]*)(>)/i", "", $str);

Forget my first attempt, using the e modifier and another preg_replace
is much better.

$return = preg_replace('!(.*?)!ie',
'preg_replace("!]*>!i", "", "$1")', $originalText);

$text = preg_replace('!(]*>.*?)(.*?)!is', '\1\2', $text);

You may also have to do this several times as this will only get one
br per  tag.

$newText = $text;
do {
  $text = $newText;
  $newText = preg_replace('!(]*>.*?)(.*?)!is', '\1\2', $text);
} while($text != $newText);

One possiblity:

echo preg_replace('/([a-z])_?([A-Z])/', '$1 $2', 
'CamerasDigital_CannonXLRshot');

explanation:
  match a lower case character preceding an uppercase character,
  with an optional underscore between them. Replace that match with
  the  matched lowercase character, space and matched uppercase character.

This will match a digit, followed by '100', followed by anything.

Unless you want to allow something like '10064893A' to match, use:

preg_match('/^100\d{5}$/', $test)

It's not a reg exp, but it will work:

if (is_numeric($val) == FALSE || strlen($val) <> 8 || substr($val, 0,
3) !== "100")
{
// $val doesn't match
}

Conversely:

if (is_numeric($val) == TRUE && strlen($val) == 8 && substr($val, 0,
3) == "100")
{
// $val does match
}

(Code not tested, but you get the idea I hope)

Hey Guys,
Solved this, took your advise and avoided regex as its an overkill.

Case you're interested:

$th_var="98797-234234--2c-something-2c";
$piece = explode("--2", $th_var);
echo $piece[0];

(and if i want to use the second "part"... $piece[1] )

Thanks to everyone who gave me examples, links and suggested alternatives
like explode(),
but personally I thought explode too was a regex..:-(.

It is easy.  I agree with whoever said string functions were a better 
solution, regexp is overkill unless there is more variaiton in the data 
than what was presented.  That said, here are some possibilities; all 
but the first assume that the "--" is always there:

- If the lengths are constant just use substr to pull out the
first 11 characters. 

- Find the "--" with strpos and then use that in a substr call to
take just the part to the left. 

- Use explode to separate the string at the "--" or "--2c". 

- For two numeric strings separated by a dash use a regexp
approach something like this: 

if (preg_match("/^(\d*-\d*)--2c/", $string, $matches))
$left_part = $matches[1];

Hey,
Thanks guys.

I did search on google first for a tutorial, problem is with something as
widely used as regular expressions
there are LOTS of results...I felt it would be better to ask if anyone has a
favourite..
ie:
if you learnt it off the web and not via the manual.

The last time I had this problem was with cookies and sessions, I found the
links I got from the people
on this list much better than the examples in the manual...after learning
from the web I did go back to the
manual and understood thing much better.

Cheers,

I will have a variable:   $the_extention

How do I take out the part which will always start with  "--2c" and will

Seems like it should be easy.

You could use preg_replaces, like so:
$result = preg_replace('/--2c.+-c/', '', $the_extention);
That matches anything between '--2c' and '-2c' and replaces it with ''.

You could also use preg_match, like so:
preg_match('/^(.+)--2c.+-c$/', $the_extention, $matches);
$matches[1] should contain the substring you need.

Chapter 7 of Learning Perl is an excellent tutorial and basic reference.

For something as simple and predictable as that using regex seems to be an 
overkill. The simple string functions ought to be adequate. explode() might 
be all you need.

in that case you should get the regex coach (easy to find via google).
it's great!

by using () around the part you want to grab.

there's lots of those. google can help you find them. try "regular

Re: [PHP] Regex help appreciated

[Mukul Sabharwal]

Firstly,

If your text spans more than one line you should use
\n, rather than just doing something like :

...(.*)

because that will mess up, depending on what text
editor you use, eg. notepad will put \r\n, but it
should only be \n. Though I'm not sure about it.

So the best solution is :

...(.*)

Now that said, let's look into your problem, you
mention you want "one" common regex that does both of
them. That would be tideous enough to let be, instead
using two distinct regex checks would be easier, and
faster.

So :

eregi('(.*)(.*)', $string, $matches);

would store "Some" in $matches[1], "more text-" in
$matches[2].

eregi('(.*)(.*)', $string,
$datex);

would store "Some text" in $datex[1], "more text" in
$datex[2]

Now if you want to know which one to execute, just do
a

if(eregi('', $input_string)) {

execute_this_Regex();

}

It should be faster this way, and an even more
efficient solution can be using Perl Regex.

I'd do something like this, unless your string must have to have the 
attributes to the html elements.

]*>[[:space:]]*]*>[[:space:]]*]*>[[:space:]]*purchasing[[:space:]]*power[[:space:]]*parity

(\s+face=\"Verdana, Arial, Helvetica, sans-serif\"|)>\s*purchasing power parity
the problem is regex is expecting something here---^

you can change it to:
(\s+face=\"Verdana, Arial, Helvetica, sans-serif\">|>)\s*purchasing power parity

OK, this is quick and nasty, but you can add sanity/error checking etc

RE: [PHP] Regex Help

[John W. Holmes]

There may be better ways, but this little example works. You basically
match everything around the  tag and run a replace on what's
outside of it, and then put it all back together. This example should
run as is. Adapt to your needs. 

test and this
test is good
This test on line 2thing
foo test on line 3
foo2
TesttestTest";

preg_match_all("/(.*)()(.*)/i",$string,$match);

$cnt = count($match[1]);

for($x=0;$x<$cnt;$x++)
{
$p1 = preg_replace("/$word/i",$repl,$match[1][$x]);
$p2 = preg_replace("/$word/i",$repl,$match[3][$x]);

$new_string .= $p1 . $match[2][$x] . $p2 . "\n";
}

echo "$string\n--\n$new_string";

?>

Re: [PHP] regex help

[Miguel Cruz]

I use this, but it's a preg rather than ereg pattern:

 '/([a-z0-9]+[a-z0-9\-]*\.)+[a-z0-9]+[a-z0-9\-]*[a-z0-9]+$/i'

Two problems (which in practice are so slight that I've foregone my usual 
standards-analness to ignore them) 

  1) It will allow a domain name component (except the final one) to end 
 with a dash (e.g., "test-.example.com").

  2) It will not allow a one-character final component.

[Jack Dempsey]

What exactly are you trying to do? "Switch around" in what way?

hi all,

a little OT here, but need some quick help. I have a bunch of e-mails to

convert into sql entries and I'm stuck here.

I have:

  , John Doe, [EMAIL PROTECTED], ..

I just need to know what's the regex to switch around the name and
e-mail 
address.

TIA,
@lvin

RE: [PHP] Regex Help

[Erick Calder]

Sheridan,

I didn't test this in PHP, I'm more familiar with the Perl Regex, but this
might work for you, play with it:

/mailto:[EMAIL PROTECTED]]

To: [EMAIL PROTECTED]
Subject:[PHP] Regex Help

I am trying to write a script that needs a list of all the images in an HTML
file.

I am trying this code

if (eregi ("(]",$buffer, $regs ))
{
  echo "$regs[2]";
}

The problem, however is that when it looks at



instead of getting images/Logo.gif like I want I am getting

images/Logo.gif ALT="Only Child Club - The Place for Only Children"

I am not as familiar with Regexes as I would like and any help would be
greatly appreciated

Thanks
