Subject: Re: [xsl] sum() over attributes is 0 From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Tue, 21 Aug 2007 20:44:49 -0300 |
<xsl:comment> <xsl:text>count: </xsl:text> <xsl:value-of select="count(//lc:container[lc:item]/@select)"/> </xsl:comment> <xsl:comment> <xsl:text>list of select attributes: </xsl:text> <xsl:for-each select="//lc:container[lc:item]/@select"> <xsl:value-of select="."/> <xsl:text> </xsl:text> </xsl:for-each> </xsl:comment>
I'm not having much success using the sum() function over a node set.
The following two expressions
<xsl:comment> <xsl:text>sum: </xsl:text> <xsl:value-of select="sum(//lc:container[lc:item]/@select)"/> </xsl:comment> <xsl:comment> <xsl:text>list of select attributes: </xsl:text> <xsl:for-each select="//lc:container[lc:item]"> <xsl:value-of select="@select"/> <xsl:text> </xsl:text> </xsl:for-each> </xsl:comment>
result in the following output:
<!--sum: 0--> <!--list of select attributes: 2 3 1 -->
I'm not clear why the result of sum() is 0. Are there any other prerequisites that I'm missing?
Thanks again.
