Python and the XML

Parser of HTML and XML with python and library Python Programming Course Tutorial Computing Learning.

There are several libraries for manipulating XML documents with Python, but this chapter is limited to a part of the standard xml package. This package provides several sub-packages:

• Dom contains minidom, an implementation of DOM in Python,
• Sax is an available implementation dictionary,
• Parsers contains the parsers used internally by DOM and SAX.

In addition, several libraries and extensions are available. They provide, for example, higher level abstractions and typed tools for a given use.
