lxml
lxml is an open source project initiated by Infrae to build a better Python binding to the popular and powerful libxml2 XML processing library. lxml tries to combine the power of libxml2 with
the ease of use of Python. Using this library, Infrae is able to build powerful XML functionality such as XPath, Relax NG, XML Schema, XSLT, and more into any application.
