nSuccess := 0

oXml := CreateObject("Chilkat.Xml")

//  Load some XML:
nSuccess := oXml:LoadXml("<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>")

? oXml:GetXml()

//  This is what we have:

//  <?xml version="1.0" encoding="utf-8"?>
//  <a>
//      <bbb>
//          <ccc>
//              <ddd>1</ddd>
//              <ddd>
//                  <z>zzz</z>
//              </ddd>
//              <ddd>3</ddd>
//          </ccc>
//      </bbb>
//  </a>

//  The TagPath property is read-only property that returns the unique path to the
//  node from the document root.

//  For example:
nFound := oXml:SearchForTag2(oXml, "z")
IF (nFound == 1)
    //  We found a node having the tag "z".
    //  The TagPath property tells us the location in the document.
    cTagPath := oXml:TagPath
    ? cTagPath

    //  The tagPath is bbb|ccc|ddd[1]|z

    //  If we to back to the document root, we can get to the given node via the tagPath.
    oXml:GetRoot2()
    ? oXml:Tag
    //  The root tag is "a".

    //  Follow the tagPath to the "z" node:
    nFound := oXml:FindChild2(cTagPath)
    ? "found = " + Str(nFound) + ", tag = " + oXml:Tag
    //  We are now at "z".
