Problems with query on different doccument

[Jonathan Robie]

The problem is in this line:

doc("casodistudio.xml")//string($name)/code

On the left side of the slash you have a string, and you are trying to 
find element children of that string. I think you are actually looking 
for some element that contains an attribute with that value. Perhaps you 
are looking for an appinfo containing a code element with an attribute 
that matches the string? Then you might use something like this:

doc("casodistudio.xml")//xs:appinfo[code/@key=$name]
