XML/DTD with DOM

[Anon]

I am trying to use the DOM XML extension in PHP 4.2.1. I have an XML file that has a linked DTD that contains default values. When I try to parse the XML file with DOM XML, it does not appear to use the DTD at all, as the default values are not there. Is there a way to do this (validating parsing?) in PHP?

Thanks for the help.
