FIgURE 13-3: 
The Walk() method makes viewing XML data easier.
Using the XMLUtil Module to View XML Data
As previously mentioned, the 
XMLUtil.py
file isn’t anything so advanced that you couldn’t put it 
together yourself, but it’s an interesting module to work with and use. Listing 13-2 shows a short 
example of how you could use this module in an application.
LISTINg 13-2: 
 Walking an XML document using XMLUtil
# Add the path required to import xmlutil. 
import sys 
sys.path.append(‘C:/Program Files/IronPython 2.6/Tutorial’)
# Import xmlutil to access the Walk() function.
import xmlutil
# Import clr to add references.
import clr
# Add the required reference.
clr.AddReference(‘System.Xml’)
# Import the System.Xml classes.
from System.Xml import *
# Create a document.
XMLDoc = XmlDocument()
# Load the XML data.
XMLDoc.Load(‘Test.XML’)
# Walk the file contents. 
print ‘Contents of Test.XML’ 
for Node in xmlutil.Walk(XMLDoc):
print ‘\nName:’, Node.Name
print ‘Value:’, Node.Value
continues
