Subject: Re: [xsl] Evaluating parameter in <xsl:when> vs evaluating parameter in <xsl:sort>. From: Jeni Tennison <jeni@xxxxxxxxxxxxxxxx> Date: Wed, 24 Jul 2002 14:12:07 +0100 |
Hi Roelf, > In the following snippet the " xalan:evaluate($sortParameter) " gets > the correct value when placed in the <xsl:sort> tag but not does not > seem to do so when placed in the <xsl:when> tag. Is there any reason > why the evaluation in the <xsl:when> tag is not working in my code? You're doing: > <xsl:when test="xalan:evaluate($sortParameter) = 'name'" > > <xsl:for-each select="query"> > <xsl:sort select="xalan:evaluate($sortParameter)" > order="ascending"/> In the test attribute of xsl:when, the context node, against which the $sortParameter expression is evaluated, is the current node in the template, whatever that is. In the select attribute of xsl:sort, the context node is the query element that you're sorting (selected by the xsl:for-each). So my guess would be that the reason that it's not working is that the context node is different in the two cases, and that doing something like: <xsl:when test="xalan:evaluate(concat('query/', $sortParameter)) = 'name'"> ... </xsl:when> would work.
