19. Ferramentas de Processamento de Markup Estruturado

O Python suporta uma variedade de módulos para trabalhar com vários formatos de marcação de dados estruturados. Isso inclui módulos para trabalhar com o Standard Generalized Markup Language (SGML) e o Hypertext Markup Language (HTML) e várias interfaces para trabalhar com o XML (Extensible Markup Language).

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.
