Okay, I think I found a way to resolve my problem, and here it is.

doc = OBJ_NEW('IDLffXMLDOMDocument', FILENAME=filename)
totalChild = (((doc->GetLastChild())-> $
GetElementsByTagName(elementName)))-> $
GetLength()

elementValue = ((((doc->GetFirstChild())-> $
GetElementsByTagName(elementName))->item(totalChild-1))-> $
GetFirstChild())->GetNodeValue()

Thank you all!
