(C++) 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>

#include <CkXml.h>

void ChilkatSample(void)
    {
    CkXml xml;

    bool success;
    //  The sample input XML is available at http://www.chilkatsoft.com/data/compress2.xml
    success = xml.LoadXmlFile("compress2.xml");
    if (success != true) {
        printf("%s\n",xml.lastErrorText());
        return;
    }

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

    //  Examine the new XML document:
    printf("%s\n",xml.getXml());

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

]]></root>


    //  Now uncompress and show that the original subtree was restored:
    xml.UnzipTree();
    printf("%s\n",xml.getXml());
