You should have a look at the ElementTree-package (which also comes api-compatible as lxml). These allow for a much more pythonic way of creating XML-trees. However you might consider using a much more concise format such as json for transport (if you have control over the client). It reduces the data-amount to about a tenth or so (of course depending on your xml-dialect), with considerable gains in processing time. And then there in fact are some template languages such as KID and genshi that might suit you because they enforce proper XML. Diez -- http://mail.python.org/mailman/listinfo/python-list
