I don't think there is a getElementsByClass function. HTML5 is proposing
one, but that will most likely be implemented in Javascript before PHP
Dom. There is a way to tidy up the HTML to make it XHTML, but I'm not
sure what it is. If you know roughly where in the document the HTML
snippet is you can use XPath to grab it.
Failing that, what about a regex? It shouldn't be too hard to write a
regex to match your example above.
