PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Xml
integer li_Found
string ls_TagPath

li_Success = 0

loo_Xml = create oleobject
li_rc = loo_Xml.ConnectToNewObject("Chilkat.Xml")
if li_rc < 0 then
    destroy loo_Xml
    MessageBox("Error","Connecting to COM object failed")
    return
end if

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

Write-Debug loo_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:
li_Found = loo_Xml.SearchForTag2(loo_Xml,"z")
if li_Found = 1 then
    // We found a node having the tag "z".
    // The TagPath property tells us the location in the document.
    ls_TagPath = loo_Xml.TagPath
    Write-Debug ls_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.
    loo_Xml.GetRoot2()
    Write-Debug loo_Xml.Tag
    // The root tag is "a".

    // Follow the tagPath to the "z" node:
    li_Found = loo_Xml.FindChild2(ls_TagPath)
    Write-Debug "found = " + string(li_Found) + ", tag = " + loo_Xml.Tag
    // We are now at "z".

end if
