AutoIt

Compress XML Tree

See more XML Examples

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>

AutoIt

Local $bSuccess = False

$oXml = ObjCreate("Chilkat.Xml")

;  The sample input XML is available at http://www.chilkatsoft.com/data/compress2.xml
$bSuccess = $oXml.LoadXmlFile("compress2.xml")
If ($bSuccess <> True) Then
    ConsoleWrite($oXml.LastErrorText & @CRLF)
    Exit
EndIf

;  Zip compress the root node's entire subtree:
$bSuccess = $oXml.ZipTree()

;  Examine the new XML document:
ConsoleWrite($oXml.GetXml() & @CRLF)

;  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:
$bSuccess = $oXml.UnzipTree()
ConsoleWrite($oXml.GetXml() & @CRLF)
