One brute force method would be to have a template that matches step and
then in this template call another template that matches for chunk and
pass down the value of the position of step to this template.
eg
<xsl:template match="Step">
<xsl:apply-templates select="descendant::Chunk[(_at_)type='FieldRef']">
<xsl:with-param name="pos" select="position()"/>
</xsl:apply-templates>
</xsl:template>
<xsl:emplate match="Chunk">
<xsl:param name="pos"/>
<!-- Field processing goes here -->
</xsl:template>
Apologies if syntax is incorrect it has been a while since I have done
XSLT and I have never used descendant, but hopefully you get at what I
am saying. I have done something similar in the past and this was the
only way I could do it. If anyone knows of a better way, I would be
grateful to find out.
Maybe you can find a way of making this more elegant by going back to
the step rather than forward to the chunk and getting the position that
way (ie, create a template that gets and prints the position of a step)

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
