lxml Description

lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language.lxml is a Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API. See the introduction for more information about background and goals.lxml.etree follows the ElementTree API as much as possible, building it on top of the native libxml2 tree. If you are new to ElementTree, start with the lxml.etree Tutorial. See also the ElementTree compatibility overview and the benchmark results comparing lxml to the original ElementTree and cElementTree implementations.Right after the lxml.etree Tutorial and the ElementTree documentation, the most important place to look is the lxml.etree specific API documentation. It describes how lxml extends the ElementTree API to expose libxml2 and libxslt specific functionality, such as XPath, Relax NG, XML Schema, XSLT, and c14n. Python code can be called from XPath expressions and XSLT stylesheets through the use of extension functions. lxml also offers a SAX compliant API, that works with the SAX support in the standard library.There is a separate module lxml.objectify that implements a data-binding API on top of lxml.etree. See the objectify and etree FAQ entry for a comparison.In addition to the ElementTree API, lxml also features a sophisticated API for custom element classes. This is a simple way to write arbitrary XML driven APIs on top of lxml. As of version 1.1, lxml.etree has a new C-level API that can be used to efficiently extend lxml.etree in external C modules, including custom element class support. Requirements: · Python What's New in This Release: Features added: · New helper functions strip_attributes(), strip_elements(), strip_tags() in lxml.etree to remove attributes/subtrees/tags from a subtree. Bugs fixed: · Namespace cleanup on subtree insertions could result in missing namespace declarations (and potentially crashes) if the element defining a namespace was deleted and the namespace was not used by the top element of the inserted subtree but only in deeper subtrees. · Raising an exception from a parser target callback didn't always terminate the parser. · Only {true, false, 1, 0} are accepted as the lexical representation for BoolElement ({True, False, T, F, t, f} not any more), restoring lxml
