<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class NodeBuilder</h1><span class="codelink"><a href="xmpp.simplexml-pysrc.html#NodeBuilder">source code</a></span><br /><br />
Builds a Node class minidom from data parsed to it. This class used
for two purposes:
<ol start="1">
<li>
Creation an XML Node from a textual representation. F.e. reading a
config file. See an XML2Node method.
</li>
<li>
Handling an incoming XML stream. This is done by mangling the
__dispatch_depth parameter and redefining the dispatch method.
</li>
</ol>
You do not need to use this class directly if you do not designing
your own XML handler.<br /><br />

Takes two optional parameters: "data" and
"initial_node". By default class initialised with empty Node
class instance. Though, if "initial_node" is provided it used
as "starting point". You can think about it as of "node
upgrade". "data" (if provided) feeded to parser
immidiatedly after instance init.
