    var xml = new chilkat.Xml();

    // Load some XML:
    var success = xml.LoadXml("<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>");

    // This is what we have:

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

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

    // For example:
    var found = xml.SearchForTag2(xml,"z");
    if (found == true) {
        // We found a node having the tag "z".
        // The TagPath property tells us the location in the document.
        var tagPath = xml.TagPath;
        console.log(tagPath);

        // 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.
        xml.GetRoot2();
        console.log(xml.Tag);
        // The root tag is "a".

        // Follow the tagPath to the "z" node:
        found = xml.FindChild2(tagPath);
        console.log("found = " + found + ", tag = " + xml.Tag);
        // We are now at "z".
