<!-- ==================== MODULE DESCRIPTION ==================== -->
<h1 class="epydoc">Module saxutils</h1><p class="nomargin-top"><span class="codelink"><a href="pyxb.utils.saxutils-pysrc.html">source code</a></span></p>
<p>This module contains support for processing XML using a SAX
parser.</p>
<p>In particular, it provides a <a
href="pyxb.utils.saxutils.BaseSAXHandler-class.html" class="link">base
content handler class</a> that maintains namespace context and element
state in a stack; and a <a
href="pyxb.utils.saxutils.SAXElementState-class.html" class="link">base
element state class</a> which records the location of the element in the
stream. These classes are extended for specific parsing needs (e.g., <a
href="pyxb.binding.saxer-module.html"
class="link">pyxb.binding.saxer</a>).</p>
