Help needed, RegEx string

[cafi]

Hi,
I'm can't get a regex to work.
What I have now is:

https?:\/\/[^\s\)\"]*

This gets all the links, but what I need is a expression that gets the all links except if image links or .exe

NamePros - Buy, Sell, Discuss Domain Names - OK

I will reward the solution with a few bucks in paypay
Thanks

Negative matching is tricky in regular expressions, and almost impossible when you don't have a strong positive match just before the negative. I'd be more inclined to search for the file type you want (e.g. html, htm, php) rather than the ones you don't. This is also going to be tricky, since you'll also want to match URLs giving just the domain name, ending with a directory name and ending with a slash.

You could use your existing regular expression and then filter out any unwanted URLs afterwards. The following code gives an example of this:

<?php

$text = '
http://www.namepros.com/images/logo-60.gif
http://www.namepros.com/wibble.jpg
http://www.namepros.com/
http://www.namepros.com
http://www.namepros.com/index.html
';

preg_match_all('#https?:\/\/[^\s\)\"]*#', $text, $matches);

echo "All URLs:\n";
print_r($matches);
echo "\n";

for ($i = count($matches[0]) - 1; $i >= 0; $i--)
{
    if (preg_match('#\.(gif|jpg|jpeg|png|exe)$#i', $matches[0][$i]))
    {
        unset($matches[0][$i]);
    }
}

echo "With images and exes removed:\n";
print_r($matches);
?>
