Re: Problem using Muenchian Method

> This works for some nodes but not others. 

it works when you're lucky and not when you're not.


/categories//category[@name=$c]//product

that's all the products below your chosen category but then 

[generate-id(@id)=generate-id(key('products-by-id', @id)[1])]

just allows through those for which the id is teh first occurrence of
that id in the whole document (your key doesn't use the category code)
so if the id appears first in some other category  it will be filtered
out completely.

The solution is to include the categroy code in your key

	<xsl:key name="products-by-id-and-category" match="@id" use="concat(ancestor::category/@name,':',.)"/>


then use key('products-by-id-and-category', concat($c,':',@id)) in your
$c case.
