Hello. I'm neither a Perl or XML expert. I was wondering if anyone could help me with a bit of code.Is it possible to create a function where you just provide the name of an XML file and it will return a true/false as to whether there is an associated DTD/schema for the XML file? I don't want to parse or validate the XML, just check for the DTD or schema existence. Can someone point me in the direction of where begin with this?
