Lisa,

thanks for that. I think that's the path I'll need to take (Pun intended).w

Cheers,
Nick

I think you need a way to select the sequence of <Step> nodes under each
<StepList> so that you can get the position of a <Step> node in the
sequence via position() function, and then call the template on the node
<Field>.

Something like this,

        <xsl:for-each select=".//StepList">
            <xsl:for-each select="./Step">
                <xsl:variable name="pos"><xsl:value-of
select="position()"/></xsl:variable>
               <xsl:apply-templates
select=".//Chunk[(_at_)type='FieldRef']/Field">
                    <xsl:with-param name="pos"><xsl:value-of
select="$pos"/></xsl:with-param>
                </xsl:apply-templates>
            </xsl:for-each>
       </xsl:for-each>


    <xsl:template match="Field">
        <xsl:param name="pos"></xsl:param>
        <xsl:value-of select="ancestor::Step[1]/@name" />
        <xsl:value-of select="$pos"/>

   </xsl:template>

In this instruction,
<xsl:value-of select="ancestor::Step[1]/ @name" /> the right side expression of the "ancestor::Step[1]/@name" produces the
attribute node of the nodes selected by the "ancestor::Step[1]", while
the right side expression of the expression
"ancestor::Step[1]/position()" yields the integers instead of nodes. I
think that's why the processor throws exception on the instruction
<xsl:value-of select="ancestor::Step[1]/position()"/>

Subject: [xsl] Finding the position of an ancestor

I was wondering if someone can help me work out a position issue I'm
struggling with.

I've got some XML that has is in it :

<FMPReport>
     <File>
         <ScriptCatalog>
             <Script>
                 <StepList>
                     <Step>
                        ...
                     </Step>
                     <Step>
                        ...
                     </Step>
                     <Step>
                        ...
                     </Step>
                     <Step id="1" name="Perform Script" enable="True">
                        <Value>
                             <DisplayCalculation>
                                <Chunk type="FieldRef">
                                     <Field id="32867" name="cPref
Server Temp Folder" table="gPrefs" />

Then in the xslt I run a for each loop

                 <xsl:for-each select="/FMPReport/File/
descendant::Chunk[(_at_)type='FieldRef']/Field">
                     <xsl:call-template name="RESULTSET" />
                 </xsl:for-each>

which works fine, and I can get the data I need.  I grab the name
from the Step using :

                     <xsl:value-of select="ancestor::Step[1]/@name" />

But how do I grab the step number?  For example I want to know that
this is step 4 in this script, by counting how many <Step> elements
there are in the current <Script> element. I thought it would just be :

                    <xsl:value-of select="ancestor::Step[1]/position
()"/>

But that doesn't work, and gives me a parsing error.  Am I maybe
going about the whole thing wrong?

Thanks,
Nick
