Package pyxb :: Package utils :: Module saxdom

Module saxdom

This module contains support for a DOM tree representation from an XML document using a SAX parser.

This functionality exists because we need a DOM interface to generate the binding classses, but the Python xml.dom.minidom package does not support location information. The SAX interface does, so we have a SAX content handler which converts the SAX events into a DOM tree.

This is not a general-purpose DOM capability; only a small subset of the DOM interface is supported, and only for storing the XML information, not for converting it back into document format.
