Identifying images referenced in HTML

[quote author="SitesByJoe" date="1234249784"]It'd be much easier to get that info with javascript being that PHP doesn't know the DOM. Is that out of the question?

If not, you're gonna have some beefy regex-type work ahead of you.[/quote]

Thanks for the input, but unfortunately this isn't a matter of live web page scraping. I'm doing this based on a user pasting raw HTML code into a form var, then saving that var and processing it on the back-end with PHP. Although, and I agree with you, that it would be easier to do this in JS, the problem is that the HTML isn't part of the DOM that I can work with. Its just raw text, so regex is a likely candidate for this.
