If you're just comparing how attractive the syntax is, that sounds
more like a python v. ruby discussion, rather than an XML-SIG
discussion. Normally in the python world the goal is to be as
pythonic as possible, which is, of course, beautiful in its own right.

Since ElementTree is included in python 2.5, I'd always give that a
shot, first:
# use xml.etree.ElementTree for a pure python implementation
import xml.etree.cElementTree as ET
# Create the root element
mytestdoc = ET.Element('mytestdoc')
# Attributes can be created with dictionaries or keyword arguments
# Add text with <object>.text
testing = ET.SubElement(mytestdoc, 'testing', {'world': 'Escape me < > !!!'})
testing.text = 'Hello World!'
person = ET.SubElement(mytestdoc, 'person')
# You can add text directly to new subnodes
ET.SubElement(person, 'comment').text = "Jim's doc is nice & friendly"
ET.SubElement(person, 'name').text = 'Jim'
# For testing, dump out the text to stdout
ET.dump(mytestdoc)
# Or, you can write it to a file
tree = ET.ElementTree(mytestdoc)
tree.write(r'C:/temp/mytestdoc.xml')
This gives you:
<mytestdoc><testing world="Escape me < >
!!!">Hello World!</testing><person><comment>Jim's doc is nice &
friendly</comment><name>Jim</name></person></mytestdoc>
ElementTree doesn't put in the xsl-stylesheet line, and it doesn't
prettyprint. http://effbot.org/zone/element-lib.htm has a short
function for that.
