func chilkatTest() {
    let xml = CkoXml()!

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

    print("\(xml.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:
    var found: Bool = xml.search(forTag2: xml, tag: "z")
    if found == true {
        // We found a node having the tag "z".
        // The TagPath property tells us the location in the document.
        var tagPath: String? = xml.tagPath
        print("\(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()
        print("\(xml.tag!)")
        // The root tag is "a".

        // Follow the tagPath to the "z" node:
        found = xml.findChild2(tagPath)
        print("found = \(found), tag = \(xml.tag!)")
        // We are now at "z".

    }
