xslt "apply-templates" question

[DoraC]

Hi,

Hmmm, I can't quite figure out how to do this with xslt. I'm extremely new to this technology, however, so I'm sure(hope?) there's an easy solution...

Let's say a portion of my to-be-transformed xml file looks as so:

<data>d1</data>
<data>d2</data>
.
.
.
<data>dn</data>

and I need to format this as text as follows:

d1,
d2,
.
.
.
dn

HOW can I code something to append a comma after the first (n-1) elements, but not the nth??? Otherwise, the resultant (output)code won't parse properly.

I've tried something like this:

<xsl:template match=&quot;some context...&quot;>
    <xsl:apply-templates select=&quot;data&quot;>
</xsl:template>

<xsl:template match=&quot;data&quot;>
    <xsl:value-of select=&quot;.&quot;/><xsl:text>,</xsl:text>
</xsl:template>

but of course this appends a comma after EVERY element, including the nth... How can I "know" when I'm at the last node of the "data"-node set, so as to avoid appending a comma? I could also prepend commas, but in that case I'd need to be able to know when I'm processing the first "data" node, so as to avoid prepending a comma to it... That might be easier, maybe? To isolate the first-node-processed case? Or is something like this patently impossible (I sure hope not!!)

Any help *greatly* appreciated.. I need to figure this out in order to generate the code I need at work!!!

Thanks!!
