This is quite workable.

First, you want to load up the second document (B.xml), so you have
it around when processing the first document (A.xml).  This should
be done at the top level.

 <xsl:variable name="doc" select="document('B.xml')"/>

Then, when processing the report template (A.xml), refer back to the
second document, and select out the relevant portions.

	<xsl:template match="category">
	 <!-- keep track of the code we want -->
	 <xsl:variable name="code" select="@code"/>

	 <!-- select products with that category code -->
	 <xsl:variable name="products"
	     select="$doc/export/product[class/category/category/@code=$code]"/>

	 <!-- process this category...-->
	 <category code="{$code}">
	  <!-- ...and process each product matching this category -->
	  <xsl:apply-templates select="$products"/>
	 </category>
	</xsl:template>

That's it.  Of course, you'll need to define templates to match 
<product/>, but that's to be expected.

Hope this helps,
