RE: [xsl] RE: Testing values from parent nodes

["M. David Peterson" <m.david@xxxxxxxxxx>]

FYI...  again, without seeing the context in which you are processing
'RR_group4' its tough to say if this is applicable, but you could also
use the following method that reduces the use of conditional logic
elements like xsl:if or xsl:choose[when][otherwise] by using the match
attribute of xsl:template to test for a particular value.  The following
tests for 3 possible values and outputs the associated text that
matches.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="text"/>
<xsl:template match="/">
  <xsl:apply-templates
select="RR/RR_row/RR_group1/RR_group2/RR_group3/RR_group4"/>
</xsl:template>
<xsl:template match="RR_group4[ancestor::RR_group2/type = 1]">
type 1
</xsl:template>
<xsl:template match="RR_group4[ancestor::RR_group2/type = 2]">
type 2
</xsl:template>
<xsl:template match="RR_group4[ancestor::RR_group2/type = 3]">
type 3
</xsl:template>
</xsl:stylesheet>
