I found the solution. The solution is in
http://groups.google.com.ec/group/prototype-scriptaculous/browse_thread/thread/37271ffc295fefbf/b8d47bc1f5cf8c66?lnk=gst&q=xml#b8d47bc1f5cf8c66
in the first paragraph :D The problem was in the way to accede to XML
file, the code syntax was bad. You must put attention with
getElementsByTagName and childs.
