Remove a string from the Element Name of XML using XSLT?

My XML looks like this.

<?xml version="1.0" encoding="utf-8"?>
 <ns0:Respuesta xmlns:ns0="http://ift.tt/1mezRKb">
  <ns0:Error>
   <ns0:Codigo>30</ns0:Codigo>
   <ns0:Descripcion>Numero no encontrado en la lista</ns0:Descripcion>
   <ns0:Sistema>adaptadorCFMS</ns0:Sistema>
   <ns0:Tipo>Adaptador</ns0:Tipo>
   <ns0:TimeStamp>2014-06-26T14:40:42</ns0:TimeStamp>
   <ns0:IdHost>medusa10</ns0:IdHost>
  </ns0:Error>
 </ns0:Respuesta>

I need to remove the 'ns0:' part of elements. It doesnt necessarily need to be 'ns0:', it can be 'ns1:' or 'ns2:, hence all those that look like that starting with 'ns' needs to be removed.

The 'ns0:' is also present as a suffix in the namespace xmlns attribute which needs to be removed too.

so the output xml should look like this.

<?xml version="1.0" encoding="utf-8"?>
 <Respuesta xmlns="http://ift.tt/1mezRKb">
 <Error>
  <Codigo>30</Codigo>
  <Descripcion>Numero no encontrado en la lista</Descripcion>
  <Sistema>adaptadorCFMS</Sistema>
  <Tipo>Adaptador</Tipo>
  <TimeStamp>2014-06-26T14:40:42</TimeStamp>
  <IdHost>medusa10</IdHost>
 </Error>
</Respuesta>

Can you please help me with this? I would really appreciate your help.
