Hi Wolfgang.
Again: Thank you for your help.
I have to tell I was going crazy. Absolutely crazy.
Then... when I decided to do it in a two step manner in which I first
combined both documents (xml) and then processed the resulting single
file to convert it to an html report, I discovered that it also gave me
empty values.
Because I'm so new to this, I didn't notice the importance of namespaces.
The examples I sent here, where "edited". I shouldn't have.
The whole problem was that the main xml documents had defined
'xmlns="..."' and the other one didn't.
All I needed to do was adding 'xmlns="" xmlns:m="..."' to the
<xsl:stylesheet headder and each time I need to read data from the main
document I need to add the 'm:' prefix.
That was it.
Forgive me for making you loose your time.
Ely.
