Just a quick regular expression question!

Hello everyone,

This should be extremely simple for youregular expression gurus out
there. I am looking for a regular expression that will look for the
hyperlinks within a string, and then add some simple code before the
hyperlinks, but only if they do not match a certain URL. For example.

$string ="This is a <a href='http://www.ur1.com'>Hyperlink</a> and this
is a <a href='http://www.ur2.com'> Hyperlink</a>";

I would like to a regular expression to look in the string for
hyperlinks that start with "http://www.ur1" and change add some code to
it like so that the string is modified like:

$string ="This is a <a
href=javascript:'http://www.ur1.com'>Hyperlink</a> and this is a <a
href='http://www.ur2.com'> Hyperlink</a>";

That's it. Thank you very much for your help!

Couldn't you find anything on Google, for example by searching on
"regex url"? If you want to append .com to links, try using
preg_replace.

Thanks! Just one more querstion. What if I wanted to match all
hyperlinks that DO NOT match a certain domain. Such as, what if I
wanted to find all URLS that do not match http://www.url1

re: Just a quick regular expression question!

so this is my regular expression:


$string_sep=preg_match_all('/(http:\/\/.+\.com)/',$page_content,$match,PREG_SET_ORDER);
for ($i = 0; $i<count($match); $i++) {
$url = $match[$i][0];
ereg('http:\/\/www\.(.*)\.com', $url, $out);
if ($out[1] != 'uctltc') {
// echo $url.'<br>';
$page_content =
ereg_replace("$url","javascript:launch('http://www.uctltc.org/common/opener.php?url=$url','window1')","$page_content");
}
}

It works! However, I need it to not only look through .com URLS, but be
open to the other extensions as well (.org, .net, .etc). And I want it
to only exampline hyperlink URLS, not image URLS, or any other sort of
URL. Thanks so much for your help! It is almost done!
