Subject: Re: [xsl] using mode in multiple template match conditions will improve speed? From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 3 May 2007 10:19:37 +0100 |
<xsl:template match="ANSWER"> you mean xsl:choose here <xsl:when test="@QTYPE='MC'"> <div class="q_mc"><!-- different class names--> <xsl:apply-templates/> </div> </xsl:when> unless you have very long lists its not likely to make so much difference but an xsl:choose is almost certainly implemented by testing each case in turn so expected time proportional to the number of choices. It looks like in this case you could do <xsl:template match="ANSWER"> <div class="q_{lower-case(@QTYPE}"> <xsl:apply-templates/> </div> </xsl:template> which is a bit more processing on the instance (the lower case has to be calculated rather than being a literal) but you avoid the conditional processing decidibng which literal to use. Only way to see which is quicker is to time it. I'd be surprised if the difference was significant but I've been wrong before.
