Re: [xsl] Defining a key on a RTF inside a Template
Subject: Re: [xsl] Defining a key on a RTF inside a Template From: Mukul Gandhi <mukul_gandhi@xxxxxxxxx> Date: Wed, 8 Dec 2004 05:43:51 -0800 (PST) |
Hi David, Thanks for your insightful comments.. You have provided the most accurate definition of the scope of xsl:key (i.e. the document node over which it operates).. But please consider this.., if for instance, the main XML document also contained the <projectsum> nodes, then the key definition - <xsl:key name="countDetail" match="projectsum" use="@id"/> would include those nodes also in the scope.. So introducing the <temp> tag would be neccessary to enforce the scope to RTF.. But I was wrong that <temp> was neccessary to enforce scope to RTF(as you have clarified).. But using <temp>(or any other name which does'nt exist in source XML) would accurately enforce the scope of xsl:key to RTF.. Am I right..?
