I'm afraid i don't understand what you're saying. Is it that if i want
to use keys i can not use document()?
no but the usage is different and it would be a waste of time to explain
one use if you want another.
You only have one document so you can just delete all document() calls.
then a key is just a way of looking up certain nodes more quickly.
First tell the system to remember them, indexing on the Menu_K child:
<xsl:key name="m" match="Menu" use="Menu_K"/>
Then in any Xpath expression you can use
key('m',wibble)
which means the same as
//Menu[Menu_K=wibble]
except it is typically much faster as the system doesn't have to search
the whole document every time: it looks them up in some kind of internal
lookup table.
so
<xsl:apply-templates
select="document('')//Menu[Menu_K=current()/MenuData]/Filhos/Menu"
mode="copia"/>
becomes
<xsl:apply-templates
select="key('m',MenuData)/Filhos/Menu" mode="copia"/>
which is less to type and faster to execute.
