Jonathan,

Thanks for the response. I'm comfortable using SAX for parsing, but
I'm unsure how it helps me with XML generation. To clarify in my
example code, with the DOM document, I can call doc.toxml() or
doc.toprettyxml(), and get the desired output (an xml file). AFAIK,
SAX has no analog, it just does parsing. Is there a way to do XML
generation with SAX that I'm unaware of?
