Demonstrates and explains the TagPath property. Visual FoxPro

LOCAL lnSuccess
LOCAL loXml
LOCAL lnFound
LOCAL lcTagPath

lnSuccess = 0

loXml = CreateObject('Chilkat.Xml')

*  Load some XML:
lnSuccess = loXml.LoadXml("<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>")

? loXml.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:
lnFound = loXml.SearchForTag2(loXml,"z")
IF (lnFound = 1) THEN
    *  We found a node having the tag "z".
    *  The TagPath property tells us the location in the document.
    lcTagPath = loXml.TagPath
    ? lcTagPath

    *  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.
    loXml.GetRoot2()
    ? loXml.Tag
    *  The root tag is "a".

    *  Follow the tagPath to the "z" node:
    lnFound = loXml.FindChild2(lcTagPath)
    ? "found = " + STR(lnFound) + ", tag = " + loXml.Tag
    *  We are now at "z".
