Demonstrates how to remove an XML subtree from an XML document. VB.NET

Dim success As Boolean = False

Dim xml As New Chilkat.Xml

success = xml.LoadXmlFile("qa_data/xml/osszes.xml")

' The XML file we're loading contains this:

' <?xml version="1.0" encoding="iso-8859-2" ?>
' <EXAMPLE>
'     <OSSZES>
'         <ROW TYPE="INS">477953
'             <NUMBER>05107003972</NUMBER>
'         </ROW>
'         <ROW TYPE="INS">477954
'             <NUMBER>05107001342</NUMBER>
'         </ROW>
'         <ROW TYPE="INS">477955
'             <NUMBER>05107001342</NUMBER>
'         </ROW>
'         <ROW TYPE="INS">477956
'             <NUMBER>05107000017</NUMBER>
'         </ROW>**
'         <ROW TYPE="INS">477957
'             <NUMBER>05107002182</NUMBER>
'         </ROW>
'     </OSSZES>
' </EXAMPLE>
' 

' We wish to remove this subtree:

' <ROW TYPE="INS">477956
'     <NUMBER>05107000017</NUMBER>
' </ROW>

' Get another reference to the XML document.
Dim xml2 As Chilkat.Xml = xml.GetSelf()

' Navigate to the node that is the root of the subtree to be deleted.
' In this case, we wish to find the node having tag "ROW" with content "477956"
Dim notUsed As String = xml2.ChilkatPath("OSSZES|/C/ROW,*477956*|$")

' Examine the xml2, it should be just the subtree.
Debug.WriteLine(xml2.GetXml())

' Now detach xml2 from the it's XML document.
' xml2 will now be it's own XML document.
xml2.RemoveFromTree()

' Examine our original XML document.  The subtree is removed:
Debug.WriteLine(xml.GetXml())
