Subject: Re: [xsl] key with restricting the scope of use attribute From: David Carlisle <davidc@xxxxxxxxx> Date: Fri, 11 May 2001 15:15:52 +0100 |
I know I've said this before but your key isn't doing anything at all. <xsl:for-each select="key('MyKey1',concat(generate-id(),':','1:1'))"> MyKey1:@id=<xsl:value-of select="@id"/><br/> </xsl:for-each> is just <xsl:if test="@x=1 and @y=1"> MyKey1:@id=<xsl:value-of select="@id"/><br/> </xsl:if> There is no for-each involved really as you are never making any use of the key. The point of a key is to hash all elements with @x and @y being 1 so you can find them quickly. You do that but then don't use it and search the document again the slow way by going <xsl:apply-templates select="/root/a[1]/b[1]"/> Then you use a key lookup that can only ever succeeed on the current node, so you know whether it will succeed before you do it.
