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

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

Hey Neil,

I'm assuming that based on your sample code and the source XML that you
are interested in the value of RR_group2/type as opposed to
RR_group1/type (which doesnt exist)?  If so, and without seeing the
context in which you are processing RR_group4, heres a sample that
should help get you where you need to go...

<?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">
  <xsl:if test="ancestor::RR_group2[type = '1']">
    hello world
  </xsl:if>
</xsl:template>
</xsl:stylesheet>

This will output "hello world" if the value of ancestor::RR_group2/type
is equal to 1.  I treated 1 as a string by using the single quotes but
this would work just as well without them given that 1 can be treated as
a string or a number by the processor.  You could also use <xsl:if
test="ancestor::RR_group2/type = '1'"> and get the same result.  The
difference between these two methods is show when they are used to
process the node and its children (as opposed to test for a value.)
"ancestor::RR_group2/type" puts 'type' into context where as
"ancestor::RR_group2[type]" puts 'RR_group2' into context if it has a
child with a local-name() of 'type'.

Let me know if this helps get you to where you need to be...

Best of luck!
