What I'm trying to accomplish with the Filter
parameter is to dynamically pass into the stylesheet a
XPath expression to be evaluated.
For example:
<xsl:param name="Filter" select="@rebate>9.99 and
@shippingMethod='Ground' and @cost<199.99"/>
<xsl:apply-templates
select="/Cat[(_at_)CatId=$Cat]/Prod[$Filter]"/>
And I think several people explained (a) that you can't do this, except
with the xx:evaluate() extension that several processors provide, and
(b) that if you do use these extensions, the select attribute must be a
string containing the expression, not the expression itself: so you need
to write:
<xsl:variable name="defaultFilter">@rebate > 9.99 and
@shippingMethod='Ground' and @cost < 199.99</xsl:variable>
<xsl:param name="Filter" select="string($defaultFilter)"/>
If you write it your way, $Filter will be the value of the expression,
not the expression itself.
