RE: Filtering based on "list" of values

Pass in the comma separated list of locations as a stylesheet parameter
$locs.

Create a global variable

<xsl:variable name="locSequence" select="tokenize($locs, ',\s+')"
as="xs:string*"/>

then select required locations as:

select="store[@location = $locSequence]"
