[norberto at ctm.ulpgc.es]

I'm trying to load a xml file with vtkXMLParse class to extract the data
wich contain it, but the class show errors like the follows:
ERROR: In /export/home/glehmann/rpm/BUILD/VTK/IO/vtkXMLParser.cxx, line 423
vtkXMLParser (0x811d038): Unknown element in XML stream: address-book

The xml file is this:
