13.4.1 Example
</H2>
<P>
The following program defines three handlers that just print out their
arguments.
<P>
<dl><dd><pre class="verbatim">
import xml.parsers.expat
# 3 handler functions
def start_element(name, attrs):
print 'Start element:', name, attrs
def end_element(name):
print 'End element:', name
def char_data(data):
print 'Character data:', repr(data)
p = xml.parsers.expat.ParserCreate()
p.StartElementHandler = start_element
p.EndElementHandler = end_element
p.CharacterDataHandler = char_data
p.Parse("""<?xml version="1.0"?>
<parent id="top"><child1 name="paul">Text goes here</child1>
<child2 name="fred">More text</child2>
</parent>""")
</pre></dl>
<P>
The output from this program is:
<P>
<dl><dd><pre class="verbatim">
Start element: parent {'id': 'top'}
Start element: child1 {'name': 'paul'}
Character data: 'Text goes here'
End element: child1
Character data: '\012'
Start element: child2 {'name': 'fred'}
Character data: 'More text'
End element: child2
Character data: '\012'
End element: parent
</pre></dl>
