(Python) Compress XML Tree

Demonstrates how to compress and restore the entire subtree rooted at an XML node.

The input XML, available at http://www.chilkatsoft.com/data/compress2.xml, is this:

<root>
    <lazydog>
        <fox>The quick brown fox jumps over the lazy dog</fox>
    </lazydog>
    <fox>The quick brown fox jumps over the lazy dog</fox>
    <child>
        <grandchild>The quick brown fox jumps over the lazy dog</grandchild>
    </child>
    <child>
        <grandchild>The quick brown fox jumps over the lazy dog</grandchild>
    </child>
</root>

import sys
import chilkat

xml = chilkat.CkXml()

#  The sample input XML is available at http://www.chilkatsoft.com/data/compress2.xml
success = xml.LoadXmlFile("compress2.xml")
if (success != True):
    print xml.lastErrorText()
    sys.exit()

#  Zip compress the root node's entire subtree:
xml.ZipTree()

#  Examine the new XML document:
print xml.getXml()

#  This is the XML w/ the compressed subtree in Base64 encoded format:
#  
<root><![CDATA[4+WyKcrPL7Hj5VIAApucxKrKlPx0KBcslJZfYReSkapQWJqZnK2QVJRfnqcAFFPIKs0tKFbIL0st
UigBSoN0KgC12uiDNECN00c1jyKzkjMyc1KQHZZelJiXAhElyUwkfTBnovDoYZGNPjTUAQ==
]]></root>


#  Now uncompress and show that the original subtree was restored:
xml.UnzipTree()
print xml.getXml()
