There's definitely something wrong with the RegEx above. The string
commences with |, so therefore the last characters of the string must be
|a - where "a" is a letter, in this case "i" meaning case-insensitive. For
some reason the |i is not at the end of the string - either you miscopied or
they misprinted.
However the RegEx doesn't strike me as correct HTML anyway, because there
can be spaces between elements, eg between "href" and "=", eg ]*)(['\" >])/i";
if ( DEBUG ) echo "RegEx=$RegEx~";
$bValidity = $iFound
= preg_match_all( $RegEx, $HTML, $aRegExOut );
An improvement might be for the closing quotes to refer back to (any)
opening quotes. I am willing to watch, listen, and learn, if anyone can
offer improvements/wisdom.

Hi Mat,
I would not please for help if I would not read those texts. Of course I've
read them both.
But on those phpbuilder's page there are also similar questions but answered
scripts don't work, for example:
$text="http://aaa\";>ttrtert";
preg_match_all("|href=\"?([^\"' >]+)|i(+[ >])", $text,$ar);
print_r($ar);
returns this:
Warning: Unknown modifier '(' in test.php on line 5 [line 5 is that line
with preg_match_all]
Array ( )
I really don't know :(

Look up Regular Expressions. Basically they allow you to search out
matches in strings such as and any variable amount of letters
between the open and closed tags. So you'd need to read in the entire
file into a string, chop out all the pesky page returns ('\n') and then
run your function using regular expressions inside of a loop of some
sort.

Subject: RE: [PHP] hyperlink parser - a bit new view :)
I think there is no message about the same idea.
I would need to parse html file and get all within href="" or href=''.
So I don't want to get all texts which could be links, but only content
of href variable within tag.
Is there any easy way ? I have read hundreds of messages in this list
today but without any possitive idea found :(
