"position in source tree" vs. "context position"
Subject: "position in source tree" vs. "context position" From: "DuCharme, Robert" <Robert.DuCharme@xxxxxxxxxx> Date: Fri, 21 Apr 2000 16:56:51 -0400 |
I'm trying to figure out the difference. The reason I ask: I understand why this template rule <xsl:template match="li"> <xsl:number value="position()" format="1. "/> <xsl:apply-templates/> </xsl:template> turns this document <litest> <li>first item</li> <li>second item</li> <li>third item</li> </litest> into this: 2. first item 4. second item 6. third item They're even numbers because the odd-numbered positions are held by the text nodes with the carriage returns after each li element. On the other hand, this template rule <xsl:template match="li"> <xsl:number format="1. "/> <xsl:apply-templates/> </xsl:template> turns the same input into this: 1. first item 2. second item 3. third item According to 7.7 of the XSLT Rec, which covers xsl:number, "If no value attribute is specified, then the xsl:number element inserts a number based on the position of the current node in the source tree." According to 4.1 of the XPath Rec, position() "returns a number equal to the context position from the expression evaluation context." Why are text nodes counted for the context position but not for the position in the source tree?
