The fundamental function you're needing here is document().
So, for example, if your file are named stock1.xml and stock2.xml,
you can access the nodes from these XML sources with
document('stock1.xml') resp. document('stock2.xml')

For example you could define a variable
<xsl:variable name="stock1" select="document('stock1.xml')" />

stock1 now contains the root node of the document in stock1.xml
It may be processed in any way you want, e.g.:
<xsl:apply-templates select="$stock1/stock/volume" />

If you just want a union (resp. a conglomerate) of both XML sources,
have a look at my merging tool at

Cheers,
