I don't think you want to use xalan:evaluate at all here. You are
creating the the variable to hold the value of <sortby>, then you want
to see if <sortby> value-of is 'name' otherwise use it as the basis for
a sort...
so you could should look like:
<xsl:variable name="sortParameter">
<xsl:value-of select="sortby"/>
</xsl:variable>
<xsl:choose>
<xsl:when test="$sortParameter = 'name'" >
<xsl:for-each select="query">
<xsl:sort select="$sortParameter" order="ascending"/>
......
</xsl:when>
<xsl:otherwise>
<xsl:for-each select="query">
<xsl:sort select="$sortParameter" order="descending"/>
If you really do need to evaluate the var as an xpath, post some more
code for more accuarate help
cheers

Hi there
In the following snippet the " xalan:evaluate($sortParameter) " gets the
correct value when placed in the <xsl:sort> tag but not does not
seem to do so when placed in the <xsl:when> tag.
Is there any reason why the evaluation in the <xsl:when> tag is not
working in my code?
....
<xsl:variable name="sortParameter">
<xsl:value-of select="sortby"/>
</xsl:variable>
<xsl:choose>
<xsl:when test="xalan:evaluate($sortParameter) = 'name'" >
<xsl:for-each select="query">
<xsl:sort select="xalan:evaluate($sortParameter)"
order="ascending"/>
......
</xsl:when>
<xsl:otherwise>
<xsl:for-each select="query">
<xsl:sort select="xalan:evaluate($sortParameter)"
order="descending"/>
....
Thanks in advance
Roelf
