See more XML Examples

Demonstrates how to remove an XML subtree from an XML document. C#

bool success = false;

Chilkat.Xml xml = 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.
Chilkat.Xml xml2 = 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"
string notUsed = 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());
