I ended up writing a third template to handle calling the first two: <xsl:template name="divideDimension"> <xsl:param name="dimension"/> <xsl:param name="divisor"/> <xsl:variable name="dimension-stripped"> <xsl:call-template name="stripUnits"> <xsl:with-param name="input" select="$dimension"/> </xsl:call-template> </xsl:variable> <xsl:variable name="result-stripped"> <xsl:value-of select="$dimension-stripped div $divisor"/> </xsl:variable> <xsl:value-of select="$result-stripped"/> <xsl:call-template name="getUnits"> <xsl:with-param name="input" select="$dimension"/> </xsl:call-template> </xsl:template> Certainly this _works_ (in the limited number of circumstances I have tested it), but is this the kind of code people are writing? It just seems rather verbose to me. If that is just a limitation of XSLT 1.0, then fine---but if it's verbose because I haven't seen a better way to code it, let me know. :-) -- Paul. mailto:paulh@xxxxxxxxxxxxxx mailto:phoadley@xxxxxxxxxxxxxxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
