regex nightmare!

Jimmy_xx

preg_match(
	"|<a[^>]+href=\"$url\"[^>]*><img[^>]+src=\"(.+?)\"[^>]*></a>|i",  $potential_pages[1], $out);

This regular expression is suppose to look in a chunk of HTML, find links pointing to a certain URL, then extract the images src within the link. It kinda works however it doesnt return just the images src, it returns everything within the image tag ie output looks like this:

[1] => http://examplesite.com/thumb/070905.jpg" border="0" style="width:100px; height:100px;">

when I want it to output this:

[1] => http://examplesite.com/thumb/070905.jpg

Any help would be greatly appreachiated!

cheers!

I think this'll work ...

<?php
$regex = "|<a[^>]+href=\"$url\"[^>]*><img[^>]+src=\"([^\"]*)\"[^>]*></a>|i";
?>

Hey Paul thanks, I've already tried that but it doesn't return anything when I do that?! perhaps its the bit inbetween the 'src="blah"' and the '>' which isn't working?

grrr regular expressions are SO annoying!

Hmm, the error might be somewhere else then because here's a controlled test...

<?php
$url = 'www.anywhere.com';
$html = '<a href="www.anywhere.com"><img src="../img/shim.gif" alt="" width="5" height="5" border="0"></a>';

$regex = "|<a[^>]+href=\"$url\"[^>]*><img[^>]+src=\"([^\"]*)\"[^>]*></a>|i";
if(preg_match($regex, $html, $out)){
	echo '<pre>';	
	print_r($out);	
	echo '</pre>';
} 
?>

... that's working fine at my end.

Paul 🙂
