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}
tr
td
{Site.id}
/td
/tr
{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);
Produces this:
Array
(
[0] = Array
(
[0] = {$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}
)
[1] = Array
(
[0] = $sites

[2] = Array
(
[0] =

[3] = Array

Keep in mind, I had to view the page source in order to see the HTML

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);

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, Todd Boyd Web Programmer -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Go to http://www.enetwizard.ws and it might make more sense. All the links on the left have an ONCLICK=location.href = '' attribute in 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 using text based browsers too.

RE: [PHP] Regex Help for URL's
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: SCRIPT LANGUAGE=JavaScriptif (parent != self) top.location.href = location.href;/SCRIPTTABLE WIDTH=1000 BORDER=0 CELLPADDING=0 CELLSPACING=0 ALIGN=CENTER CLASS=TEMPLATE-TABLETRTD COLSPAN=7 CLASS=TEMPLATE-TABLE-TOP TABLE BORDER=0 CELLPADDING=0 CELLSPACING=0 WIDTH=100% HEIGHT=48 TR TD WIDTH=60 ROWSPAN=2 ALIGN=RIGHTIMG SRC=http://www.enetwizard.info/shared/enetwizard.gif; WIDTH=46 HEIGHT=46 BORDER=0 ALT= //TD TD HEIGHT=24 VALIGN=BOTTOMDIV STYLE=font-family: sans-serif; font-size: 8pt; font-weight: bold; color: white; margin-left: 10px;eNetwizard, Inc./DIV/TD TD HEIGHT=24 VALIGN=BOTTOM ALIGN=RIGHTDIV STYLE=font-family: sans-serif; font-size: 8pt; color: #FF; font-weight: bold; margin-right: 20px; Anonymous Visitornbsp;nbsp;|nbsp;nbsp;A HREF=http://www.enetwizard.cc/security.wizard?asset=welcomeamp;process=log inamp;form=login STYLE=font-family: sans-serif; font-size: 8pt; color: #6BDB17; font-weight: bold; text-decoration: underline;Log In/Anbsp;nbsp;|nbsp;nbsp;A HREF=http://www.enetwizard.cc/security.wizard?asset=welcomeamp;process=sig nupamp;form=signup STYLE=font-family: sans-serif; font-size: 8pt; color: #6BDB17; font-weight: bold; text-decoration: underline;Sign Up/A /DIV/TD /TRTR TD HEIGHT=24 VALIGN=TOPDIV STYLE=font-family: sans-serif; font-size: 8pt; color: white; margin-left: 10px;IEmpowering Your Creativity./I/DIV/TD TD HEIGHT=24 VALIGN=TOP ALIGN=RIGHTDIV STYLE=font-family: sans-serif; font-size: 8pt; color: #FF; margin-right: 20px; ITuesday, May 16, 2006/I /DIV/TD /TR /TABLE /TD/TRTRTD COLSPAN=7 STYLE=height: 20px;DIV STYLE=font-size: 1px;nbsp;/DIV/TD/TRTRTD VALIGN=TOP STYLE=width: 20px;DIV STYLE=font-size: 1px;nbsp;/DIV/TDTD VALIGN=TOP CLASS=TEMPLATE-TABLE-LEFT STYLE=width: 180px;TABLE CLASS=RSW-TABLETR CLASS=RSW-TABLE-HEAD-TRTD CLASS=RSW-TABLE-HEAD-TDDIV CLASS=RSW-DIV-HEAD-CENTERSPAN CLASS=RSW-FONT-HEAD-TEXTeNetwizard, Inc./SPAN/DIV/TD/TRTR CLASS=RSW-TABLE-ROW1-TRTD CLASS=RSW-TABLE-ROW1-TD ONMOUSEOVER=this.className = 'RSW-TABLE-SEP1-TD'; window.status = 'Backend Manager'; return true; ONMOUSEOUT=this.className = 'RSW-TABLE-ROW1-TD'; window.status = ''; return true; ONCLICK=location.href = 'http://www.enetwizard.be/default.rsw'; return true; STYLE=cursor: pointer;DIV CLASS=RSW-DIV-ROW1-LEFTSPAN CLASS=RSW-FONT-ROW1-TEXTA CLASS=RSW-FONT-ROW1-LINK HREF=http://www.enetwizard.be/default.rsw; ONMOUSEOVER=window.status = 'Backend Manager'; return true; ONMOUSEOUT=window.status = ''; return true;Backend Manager/ABReNetwizard.be/SPAN/DIV/TD/TRTR CLASS=RSW-TABLE-ROW2-TRTD CLASS=RSW-TABLE-ROW2-TD ONMOUSEOVER=this.className = 'RSW-TABLE-SEP2-TD'; window.status = 'Business Headquarters'; return true; ONMOUSEOUT=this.className = 'RSW-TABLE-ROW2-TD'; window.status = ''; return true; ONCLICK=location.href = 'http://www.enetwizard.biz/default.rsw'; return true; STYLE=cursor: pointer;DIV CLASS=RSW-DIV-ROW2-LEFTSPAN CLASS=RSW-FONT-ROW2-TEXTA CLASS=RSW-FONT-ROW2-LINK HREF=http://www.enetwizard.biz/default.rsw; ONMOUSEOVER=window.status = 'Business Headquarters'; return true; ONMOUSEOUT=window.status = ''; return true;Business Headquarters/ABReNetwizard.biz/SPAN/DIV/TD/TRTR CLASS=RSW-TABLE-SEP1-TRTD CLASS=RSW-TABLE-SEP1-TD ONMOUSEOVER=this.className = 'RSW-TABLE-SEP1-TD'; window.status = 'Client Control Center'; return true; ONMOUSEOUT=this.className = 'RSW-TABLE-SEP1-TD'; window.status = ''; return true; ONCLICK=location.href = 'http://www.enetwizard.cc/default.rsw'; return true; STYLE=cursor: pointer;DIV CLASS=RSW-DIV-SEP1-LEFTSPAN CLASS=RSW-FONT-SEP1-TEXTA CLASS=RSW-FONT-SEP1-LINK HREF=http://www.enetwizard.cc/default.rsw; ONMOUSEOVER=window.status = 'Client Control Center'; return true; ONMOUSEOUT=window.status = ''; return true;Client Control Center/ABReNetwizard.cc/SPAN/DIV/TD/TRTR CLASS=RSW-TABLE-ROW2-TRTD CLASS=RSW-TABLE-ROW2-TD ONMOUSEOVER=this.className = 'RSW-TABLE-SEP2-TD'; window.status = 'Development Services'; return true; ONMOUSEOUT=this.className = 'RSW-TABLE-ROW2-TD'; window.status = ''; return true; ONCLICK=location.href = 'http://www.enetwizard.de/default.rsw'; return true; STYLE=cursor: pointer;DIV CLASS=RSW-DIV-ROW2-LEFTSPAN CLASS=RSW-FONT-ROW2-TEXTA CLASS=RSW-FONT-ROW2-LINK HREF=http://www.enetwizard.de/default.rsw; ONMOUSEOVER=window.status = 'Development Services'; return true; ONMOUSEOUT=window.status = ''; return true;Development Services/ABReNetwizard.de/SPAN/DIV/TD/TRTR CLASS=RSW-TABLE-ROW1-TRTD CLASS=RSW-TABLE-ROW1-TD ONMOUSEOVER=this.className = 'RSW-TABLE-SEP1-TD'; window.status =

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 [ANSWER]
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: A HREF=javascript:void(0); ONCLICK=javascript:window.open = '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++) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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+/
Ideally what I want to do is update the db table that holds these records.
ID: 1
Unit: 102-90 E 42 X 42 X 70 3/8
Panel: 42
Width: 42
Height: 70 3/8
If this is the case, where does the 102-90 E come from? This sounds
more like a data normalization issue than anything.

If this string is always in this format
xxx E panel X width X height
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]);

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: !-- START PRINT -- various html crap here !-- END PRINT -- Here's the regex I'm using: /!-- START PRINT --(.*?)!-- END PRINT --/ 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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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(/!-- START PRINT --(.*?)!-- END PRINT --/s, $str, $out); http://php.planetmirror.com/manual/en/reference.pcre.pattern.modifiers.php Hope this helps.

success with this, which is pretty thorough:
^(?:[\w\!\#\$\%\\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\\'\*\+\-
\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}
[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|
(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]
\d|25[0-5])\]))$
Which I got from here:

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
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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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)

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 need a validation regex that will pass a string. The string can

characters except two consecutive ampersands () anywhere in the
string.
I'm stumped - ideas?
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;
$testStrings = array(
'a',
'g',
'df',
'adfdf',
'adfsdfff',
'ff',
'dfds',
'dsdf',
'ddf',
'dff'
);
foreach ($testStrings as $string) {
if (preg_match(/^(?:()(?!)|[^]){1,$maxLen}$/, $string)) {
print $string matches.\n;
} else {
print $string does not match.\n;
}
}

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}$/
Or if you don't care about capturing portions of the match and then throwing
them away:
/^((?!)|[^]){1,5}$/

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
$str = preg_replace('/head.*[\/]head/Uis','',$str);
// strip out non product images
$str =
preg_replace('/img[^]*(nieuw|new|euro)\.gif[^]*\/?/Uis','',$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?
$str = preg_replace('/table.*hr/Uis','',$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);

Re: [PHP] regex help
Forget my first attempt, using the e modifier and another preg_replace
is much better.
$return = preg_replace('!h(\d)(.*?)/h\1!ie',
'preg_replace(!br[^]*!i, , $1)', $originalText);

I can grab the beginning of the tag easily, but my

not an option at this point.
$text = preg_replace('!(h\d[^]*.*?)br/(.*?/h\d)!is', '\1\2', $text);
You may also have to do this several times as this will only get one
br per h tag.

Simple:
while (preg_match(/(h\d)(.*)(br \/)(.*)(\/h\d)/is, $str)) {
$str = preg_replace(/(h\d)(.*)(br \/)(.*)(\/h\d)/is,
$1$2$4$5, $str);

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

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.

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.

Re: [PHP] Regex help appreciated
Firstly,
If your text spans more than one line you should use
\n, rather than just doing something like :
a href=\
hello\...(.*)/a
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 :
a href=\\nhell\...(.*)/a
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('para font-size=12 font-family=Arial
style=heading 2(.*)anchor
type=bkmrk/(.*)/para', $string, $matches);
would store Some in $matches[1], more text- in
$matches[2].
eregi('para font-size=12 font-family=Arial
style=heading 2inline
caps=false(.*)/inline(.*)/para', $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('inline caps=false', $input_string)) {
execute_this_Regex();
}
It should be faster this way, and an even more
efficient solution can be using Perl Regex.

RE: [PHP] Regex Help
There may be better ways, but this little example works. You basically
match everything around the option 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.
?
header(Content-type: text/plain);
$word = test;
$repl = anotherword;
$new_string = ;
$string =
This test is a test okay? option value='test'test/option and this
test is good
This test on line 2option value='whatever'thing/option
option value='foo'foo/option test on line 3
option value='foo2'foo2/option
Testoptiontest/optionTest;
preg_match_all(/(.*)(option.*option)(.*)/i,$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
Instead of splitting the string on chars that don't equal \w and ',
split it on chars that equal \s (or any other you need)

Could my regex be expanded to handle non-english type characters, or
any workarounds to get a string into an array of words,
where the string contains non english characters??

Re: [PHP] regex help
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.

On Sun, 26 May 2002, Jeff Field wrote:
This is not really specific to PHP (although the information might be useful
for all that form validation we all do), and for that I apologize in advance
(does anyone know of a regex mailing list?), but maybe someone here can help
with the following:
I find no good regex for checking valid domain names. None that I have seen
take into account the fact that, although dashes (-) and dots (.) are
allowed in a domain name, the domain name can neither begin with nor end
with a dash or dot, and additionally, two dashes or two dots in a row are
not allowed and a dash followed by a dot or a dot followed by a dash are not
allowed.
So, I've come up with two regex's for checking domain names. The first one
checks that the name contains alphanumerics, the dash and the dot, and
neither begins with or ends with a dash or dot:
^[a-z0-9]$|^[a-z0-9]+[a-z0-9.-]*[a-z0-9]+$
The second one checks that two dashes and two dots are not together and that
a dash followed by a dot or a dot followed by a dash are not together:
--|\.\.|-\.|\.-
Putting it all together, the way I check for a valid domain name is with the
following:
if (eregi(^[a-z0-9]$|^[a-z0-9]+[a-z0-9.-]*[a-z0-9]+$, $domain_name) !=
true
OR eregi(--|\.\.|-\.|\.-, $domain_name) == true
{
error;
}
So, my question (finally!) is this:
Is there any way to combine both expressions (basically, one part that
checks for false and one part that checks for true) into one regex that just
returns true or false? I haven't been able to find any documentation that
shows me how to do that, basically a like this but not like this syntax.
BTW, anticipating someone mentioning the fact that the above regex's don't
check for a domain name ending with a dot followed by three characters max
(as in .com, .net, etc.), it's because that long-held truth is no longer
true. We now have .info and .museum, and who know what the future will
bring.
About the only truth left is that domain names end in a dot followed by two
characters minimum (there are the country code domains like .us, .de. etc.
but there are no one character TLD's at present and I would expect perhaps
not for a long long time, but you never know). Perhaps someone would expand
on the regex above to include checking for a name ending with a dot followed
by two characters minimum, I just haven't been into regex's long enough to
know how).
Of course, you could get really anal about all this and check for domain
names that only end in the current ICANN root server TLD's (about 260 or so,
I believe), but that wouldn't account for TLD's that operate within other
root servers (there's always sumthin'). Anyways,
Any help with the above is certainly appreciated!

RE: [PHP] Regex Help
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:
/img\s*src=([^ ]*)/
note: \s = whitespace and the [^ ] means any nonspace character... the only
issue remaining that you might find s or 's around the string matched into
the ().
