19. 结构化标记处理工具

Python 支持各种模块，以处理各种形式的结构化数据标记。 这包括使用标准通用标记语言（SGML）和超文本标记语言（HTML）的模块，以及使用可扩展标记语言（XML）的几个接口。

It is important to note that modules in the xml package require that there be at least one SAX-compliant XML parser available. Starting with Python 2.3, the Expat parser is included with Python, so the xml.parsers.expat module will always be available. You may still want to be aware of the PyXML add-on package; that package provides an extended set of XML libraries for Python.

The documentation for the xml.dom and xml.sax packages are the definition of the Python bindings for the DOM and SAX interfaces.
