Definitely use XML::Checker from Perl, or use an external parser as KM suggested.

Once and for all: expat, the underlying parser for XML::Parser is _NOT_ a validating parser. It only check for well-formedness (whether the document is tagged properly, no DTD involved).

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
