After some more research I think I must use a combination of two techniques:

a) Recursive named template (example: "String split into elements" -> 
http://www.dpawson.co.uk/xsl/sect2/N7240.html#d9570e343 ).
b) <xsl:key> (example: "Replacing a string by another which is found by 
reference in the same XML document" -> 
http://www.dpawson.co.uk/xsl/sect2/N7240.html#d9570e109 ).

Am I correct?

   Thanks in advance.
