Is there a best way to do > this in XSL? yes, first restructure your map as associating a key and value by position is a bad idea, much better to use attributes: <map> <key name="12345" value="abcde"/> <key name="78910" value="lmnop"/> </map> then define a key to return a value for a given name: <xsl:key name="mappings" match="key" use="@name"/> then in xslt 1.0 use: <xsl:variable name="lookup" select="the_name_you_want_lookup"/> <xsl:for-each select="$map"> <xsl:value-of select="key('mappings', $lookup)/@value"/> </xsl:for-each> in 2.0 you don't have the hassle of switching the context node because key() can take it as the third argument: <xsl:value-of select="key('mappings', the_name_you_want_to_lookup, $mappings)/@value"/> cheers andrew
