> So, how can I look at another set of elments.

By using the document() function.  Here is one way -

<xsl:variable name='hierarchy-structure-table'
   select='document("herarchy_structure_table.xml")'/>

Now $hierarchy-structure-table will be the root of the document
containing the structural tables.  You can select any node or node set
you want from it.

Cheers,
