Regex to find image from content

Question

I am trying to find the first image from the content. Using Regex

<imgs+((width|height|border|classs|id|src|usemap|hspace|vspace)=”[^"]+”s*)+>

The function is used as

<?php
$content="<img src='s' height='20' >";

preg_match("/<imgs+((width|height|border|classs|id|src|usemap|hspace|vspace)=”[^"]+”s*)+>
/" ,$content,$matches);
var_dump($matches);
?>

But i get a syntax error. I want to handle all possible cases for img tags, how can this be done? I need the src attribute of the tag.

Use some sort of HTML parsing library. You cannot use regex to parse HTML: http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags — James Wiseman, May 18 '12 at 09:42
I need the value assigned to height|width| source part, between the " quotes. — Amna Ahmed, May 18 '12 at 09:55

You won't be able to catch all possible cases with a regex. HTML generally can not be successfully parsed using only regular expression matching - it's just too complex.

You will need to use a proper html parser, or limit yourself to a subset of possible solutions.
