(VB.NET UWP/WinRT) 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>

Dim xml As New Chilkat.Xml

Dim success As Boolean
' The sample input XML is available at http://www.chilkatsoft.com/data/compress2.xml
success = xml.LoadXmlFile("compress2.xml")
If (success <> True) Then
    Debug.WriteLine(xml.LastErrorText)
    Exit Sub
End If


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

' Examine the new XML document:
Debug.WriteLine(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:
success = xml.UnzipTree()
Debug.WriteLine(xml.GetXml())
