<!-- ==================== MODULE DESCRIPTION ==================== -->
<h1 class="epydoc">Module saxdom</h1><p class="nomargin-top"><span class="codelink"><a href="pyxb.utils.saxdom-pysrc.html">source code</a></span></p>
<p>This module contains support for a DOM tree representation from an XML
document using a SAX parser.</p>
<p>This functionality exists because we need a DOM interface to generate
the binding classses, but the Python <code>xml.dom.minidom</code> 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.</p>
<p>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.</p>
