Parsing XML with DTD

Hey all, I've been asked if it's possible to parse XML files given a DTD file that describes the elements within it, so I've been looking through the docs at php.net. So far I've found this: http://us.php.net/manual/en/ref.xml.php Which has some samples on, but nothing that I see will take a DTD file and parse the XML accordingly. I'm thinking something like this is probably possible. I'm still looking through the docs, but if anyone can point me in the right direction would be appreciated. Thanks!
