Subject: [xsl] Allowing whitespace to stop merge of adjacent nodes From: Matt Sims <matt.sims@xxxxxxxx> Date: Tue, 10 Oct 2006 11:39:12 +0100 |
I'm using the following stylesheet to merge adjacent nodes of a particular type and sum their attributes:
<?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:aston="http://www.aston.tv/schemas/Aston/Aston7">
<xsl:template match="node()"> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates select="node()[1]"/> </xsl:copy> <xsl:apply-templates select="following-sibling::node()[1]"/> </xsl:template>
<xsl:template match="aston:offset[not(node())]"> <xsl:param name="a" select="/.."/> <xsl:choose> <xsl:when test="following-sibling::node()[self::* or normalize-space(.)][1]/self::aston:offset[not(node())]"> <xsl:apply-templates select="following-sibling::aston:offset[1]"> <xsl:with-param name="a" select="$a|@*"/> </xsl:apply-templates> </xsl:when> <xsl:otherwise> <offset xmlns="http://www.aston.tv/schemas/Aston/Aston7" x="{sum($a[name()='x']|@x)}" y="{sum($a[name()='y']|@y)}" z="{sum($a[name()='z']|@z)}" /> <xsl:apply-templates select="following-sibling::node()[1]"/> </xsl:otherwise> </xsl:choose> </xsl:template>
<text> Hello<offset x="2" y="4" /><offset x="3" y="2" />World </text>
<text> Hello<offset x="5" y="6" />World </text>
My problem occurs if I have a whitespace character between the two adjacent nodes, like so:
<text> Hello<offset x="2" y="4" /> <offset x="3" y="2" />World </text>
In this case, I wouldn't expect the nodes to be merged as they're not strictly adjacent (there's a whitespace node between them) - but they are!
