(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>

Chilkat.Xml xml = new Chilkat.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) {
    textBox1.Text += xml.LastErrorText + "\r\n";
    return;
}

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

//  Examine the new XML document:
textBox1.Text += xml.GetXml() + "\r\n";

//  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();
textBox1.Text += xml.GetXml() + "\r\n";
