Structured Markup Processing Tools
**********************************

Python supports a variety of modules to work with various forms of
structured data markup.  This includes modules to work with the
Standard Generalized Markup Language (SGML) and the Hypertext Markup
Language (HTML), and several interfaces for working with the
Extensible Markup Language (XML).

* "html" --- HyperText Markup Language support

  * Example HTML Parser Application

  * "HTMLParser" Methods

  * Examples

* "html.entities" --- Definitions of HTML general entities
