    copied!<p>Python is great at handling XML, I consider <a href="http://codespeak.net/lxml/" rel="nofollow">lxml</a> to be the best xml library I have ever worked with, it is powerful and significantly simpler the DOM. The namespace handling took some getting used to, but I think it is another great way lxml keeps things simple.</p> <p><strong>EDIT</strong></p> <p>After re reading the question, it is unclear exactly whether the the author meant the serialization of python objects, or just the DOM tree. The portion of my answer bellow assumed the former.</p> <p>XML serialization is a completely different issue. Personal I don't think it is very important. Most XML serializers produce output that its pretty specific to the language or runtime, which defeats the purpose of having such an open format. I realize that there are some generic XML serialization schema, but Python provides 2 solutions that are superior for 95% of situations, Pickling and JSON.</p> <p>If your application doesn't have to share objects with non-python systems, Pickling is the fastest and most powerful serialization solution you will find. JSON is significantly faster to parse and generate, and much easier to work with than XML. JSON has plenty of limitations, but it is frequently easier to work around them, than deal with the headaches of XML.</p> <p>There are plenty of other serialization formats that, depending on the application, I would recommend ahead of XML (E.G.: Google Protocol Buffers, or YAML.)</p> <p>Also, don't forget about SAX. Event driven parsers are only useful for reading XML, but I have found that it is still the best solution for some problems.</p>
