Give LibXML a look. It might be what you need.
NSGMLS is old but good.

If you want to validate against a DTD, most parsers assume you have a
DOCTYPE declaration in the XML document. However, it fairly easy to work
around this, for example by prepending a DOCTYPE declaration before
handing the document over to the parser. (If your files have an XML
declaration, you will have to strip it off before prepending the
DOCTYPE.)
You can also generate the DOCTYPE declaration and then include your
document using an entity.
