[xsl] Question about position()

["rick@xxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi All,



I am creating sorted variable in order to use as a lookup later. Later, I
want to loop through the nodes and return its code attribute value one at a
time. When I use the position() function as a predicate, it returns all of
the attributes instead of the one at that position. If I put a hard-coded
number in as the predicate, it returns a single value, which is what I
expect. I am missing something fundamental here. Thank you for the help.

        <feature code="5551" text="Shelf life greater than 2 years"/>

        <list count="3"/>
