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.
<xsl:template match="Step"> <xsl:apply-templates select="descendant::Chunk[@type='FieldRef']"> <xsl:with-param name="pos" select="position()"/> </xsl:apply-templates>
<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 :
<Step id="1" name="Perform Script" enable="True">
<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[@type='FieldRef']/Field">
<xsl:call-template name="RESULTSET" />
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/@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/ position ()"/>
But that doesn't work, and gives me a parsing error. Am I maybe going about the whole thing wrong?
