Support XML files in datagen

This should interact well with any potential HTML support.

Any preference on which parser we use?
I am looking at
JDOM https://www.tutorialspoint.com/java_xml/java_dom_parse_document.htm
XOM http://xom.nu/
and DOM4J https://dom4j.github.io/

Any reason to not use the built in XML processing in JDK? Also I would vote for any that use a DOM representation (vs a SAX event model) so that the translation to Boa AST is similar to other languages.

Hi Bob,

I saw you added code for parsing XML.
Could you tell us a bit about your choice for the parser?

I did some google searches on XML dom parsers and this one was well rated, it was also open source on github which helped design the visitor.
