Re: [xsl] Avoiding multiple "apply-templates" by creating one variable for the clauses. Is it possible?

Hi,

   <xsl:choose>
       <xsl:when test="$AuthorId">
         <xsl:apply-templates select="//blog[author_id = $AuthorId]"/>
       </xsl:when>
       <xsl:when test="$CategoryId">
         <xsl:apply-templates select="//blog[category_id = $CategoryId]"/>
       </xsl:when>
       <xsl:when test="$AuthorId and $CategoryId">
         <xsl:apply-templates select="//blog[author_id = $AuthorId and category_id = $CategoryId]"/>
       </xsl:when>
       <xsl:otherwise>
         <xsl:apply-templates select="//blog"/>
       </xsl:otherwise>
     </xsl:choose>

Would this code have worked anyway? The XSLT 2.0 spec (8.2) reads:

"The content of the first, and only the first, xsl:when element that is satisfied is evaluated". I suppose it's the same in XSLT 1.0.

So I wonder if the third xsl:when would execute at all, because if either
$AuthorId or $CategoryId evaluate to true, one of the first two xsl:when
should be satisfied.
