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

#include <CkXml.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkXml 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.
    CkXml *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"
    const char *notUsed = xml2->chilkatPath("OSSZES|/C/ROW,*477956*|$");

    //  Examine the xml2, it should be just the subtree.
    std::cout << xml2->getXml() << "\r\n";

    //  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:
    std::cout << xml.getXml() << "\r\n";

    delete xml2;
    }
