Not too sure what you mean. As I understand it, if you have a template
match for Step, if will give you position of Step in relation to node
set you selected. If you select all Step values anywhere //Step
you will probably get the position of the Step values as they appear in
the nodeset (I think). If someone could confirm this for me, it would be
very helpful.
So, to answer your question, I think it depends on how you call the
template match for Step.

Thanks Kamal,
Yes, that was something I thought of, but hadn't tried yet. The only
issue is that if there are multiple <script> elements, does the
position reset each time so that it starts again at 1 for each new
group of <Step> elements?

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
