How to generate XML

Others have mentioned DOM.  You can also use SAX to
generate XML, if you're careful.

from xml.sax import saxutils
gen = saxutils.XMLGenerator()

gen.startDocument()
gen.startElement("begin", {})
gen.characters("some <text> that gets &escaped;\n")
gen.endElement("begin")
gen.endDocument()

prints the following

<?xml version="1.0" encoding="iso-8859-1"?>
<begin>some <text> that gets &escaped;
</begin>

I've written a few tree traveral algorithms which
mimic the SAX event mechanism.  Makes it very easy
to convert the tree to XML.
