My code looks like this:

if (!empty($foo))
    $doc = new DOMDocument();
    $images = $doc->getElementsByTagName('img');

And this is happening:

DOMDocument::loadHTML() [<a href='domdocument.loadhtml'>domdocument.loadhtml</a>]: Document is empty in Entity, line: 2

Re: DOMDocument 80 80

$foo is an empty string or has invalid markup.

See the second comment (by Shane Harter) here.

Re: DOMDocument 80 80

Odd because $foo just finished getting passed through HTML Purifier.
