Are there built-in XML parsers in Python?
In Part I, we looked at some of Python’s built-in XML parsers. In this chapter, we will look at the fun third-party package, lxml from codespeak. It uses the ElementTree API, among other things. The lxml package has XPath and XSLT support, includes an API for SAX and a C-level API for compatibility with C/Pyrex modules. Here is what we will cover:
Can you use lxml with Python 3.2?

Anyway, once you have it installed, we can start going over this wonderful piece of XML again:
How to parse an XML file in lxml?
The last piece of the puzzle is to get lxml to generate the XML itself. Here we use lxml’s etree module to do the hard work: The tostring function will return a nice string of the XML and if you set pretty_print to True, it will usually return the XML in a nice format too.
