Subject: RE: [xsl] tail recursion and NaN From: "Susan Campbell" <SCampbell@xxxxxxxxxxxxxx> Date: Fri, 7 May 2004 08:59:19 -0400 |
Thanks for the help. I later learned I also had to test for a dollar sign as well as empty cells. This is what I'm using. It works, but there may be a more compact/elegant way to do it. sc <xsl:template name="total-value"> <xsl:param name="price"/> <xsl:param name="result" select="0"/> <xsl:param name="nodollarsign" select="translate($price,'$','')"/> <xsl:choose> <xsl:when test="$price and number($price) = number($price)"> <xsl:call-template name="total-value"> <xsl:with-param name="price" select="$price[position() > 1]"/> <xsl:with-param name="result" select="$result + $price"/> </xsl:call-template> </xsl:when> <xsl:when test="$nodollarsign"> <xsl:call-template name="total-value"> <xsl:with-param name="price" select="$price[position() > 1]"/> <xsl:with-param name="result" select="$result + $nodollarsign"/> </xsl:call-template> </xsl:when> <xsl:when test="$price and number($price) != number($price)"> <xsl:call-template name="total-value"> <xsl:with-param name="price" select="$price[position() > 1]"/> <xsl:with-param name="result" select="$result"/> </xsl:call-template> </xsl:when> <xsl:otherwise><xsl:value-of select="$result"/></xsl:otherwise> </xsl:choose> </xsl:template>
