Procedure Test
    Variant vXml
    Handle hoXml
    Boolean iSuccess
    Boolean iFound
    String sTagPath
    String sTemp1

    Get Create (RefClass(cComChilkatXml)) To hoXml
    If (Not(IsComObjectCreated(hoXml))) Begin
        Send CreateComObject of hoXml
    End

    // Load some XML:
    Get ComLoadXml Of hoXml "<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>" To iSuccess

    Get ComGetXml Of hoXml To sTemp1
    Showln sTemp1

    // 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:
    Get pvComObject of hoXml to vXml
    Get ComSearchForTag2 Of hoXml vXml "z" To iFound
    If (iFound = True) Begin
        // We found a node having the tag "z".
        // The TagPath property tells us the location in the document.
        Get ComTagPath Of hoXml To sTagPath
        Showln sTagPath

        // 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.
        Send ComGetRoot2 To hoXml
        Get ComTag Of hoXml To sTemp1
        Showln sTemp1
        // The root tag is "a".

        // Follow the tagPath to the "z" node:
        Get ComFindChild2 Of hoXml sTagPath To iFound
        Get ComTag Of hoXml To sTemp1
        Showln "found = " iFound ", tag = " sTemp1
        // We are now at "z".
