Re: [xsl] Get nodes with document() and applying templates to them

[David Carlisle <davidc@xxxxxxxxx>]

  BTW, when i do 

  <xsl:apply-templates
  select="document('TreeMenu.xml')//Menu[Menu_K=current()/MenuData]/Menu"
  />

  what is hapening? Does the entire TreeMenu.xml loads and then get the
  nodes selected, or by some magic only the nodes selected are being
  loaded?


You are not supposed to ask. That is if the system can apply magic to
download less of that document (or less of the original source document)
than is apparently requested then this just comes under the "invisible
optimisation" implementation details banner.

However it's safest to assume that the whole document is
loaded. Specifically because in the template for Menu that is applied by
the above you are free to go
<xsl:value-of select="../../.."/>
so if the system had magically only fetched the  Menu nodes it had
better magically fetch the great-grandparents of those nodes when it
comes to this command.
