In that case, you should read up on XML in general first.

If you want to use DTDs, e.g. to do validation, to inject default attributes, or to resolve entity references, you can switch to the external lxml.etree package. Note, however, that lxml does not support the ".entity" dictionary on parsers. It doesn't currently have a way to override entity definitions outside of a DTD.
