Thanks Andrew,
To complete the thread, and just in case anyone else is searching this
list for incrementing code, here is mine:
<xsl:variable name="NUMIMAGES">
<xsl:value-of select
="count(/NewsML/NewsItem/NewsComponent/NewsItem/NewsComponent/NewsComponent/ContentItem/Encoding/DataContent)"
/>
</xsl:variable>
<td><xsl:for-each select =
'//Encoding/DataContent'>
<xsl:element name="a">
<xsl:attribute
name="href"><xsl:value-of select="$page-name"/>.<xsl:value-of select =
"$NUMIMAGES - position() + 1"/>.jpg</xsl:attribute>

</xsl:for-each>

I suppose the simplest thing to do here is to minus the position() of
the current element in the for-loop, thereby decrementing the value each
time:
value="$NUMIMAGES - position() + 1"
instead of 1.
cheers

Subject: [xsl] incrementing a variable
Hi,
I am having difficulties with the following piece of code. I wish to
decrement the value of $NUMIMAGES on each iteration of a
for-each loop.
However instead of the desired effect, which is to create links to
images based on the name of the page($page-name) and the number of
images in each page. I am simply getting multiple links to the same
image where $NUMIMAGES still has it's initial value from the
count function.
I am sure that, as ever the answer is easy. Can anyone help?
<xsl:variable name="NUMIMAGES">
<xsl:value-of select
="count(/NewsML/NewsItem/NewsComponent/NewsItem/NewsComponent/
NewsComponent/ContentItem/Encoding/DataContent)"
/>
</xsl:variable>
<td><xsl:for-each select =
'//Encoding/DataContent'>
<xsl:element name="a">
<xsl:attribute name="href">
<xsl:value-of
select="$page-name"/>.<xsl:value-of
select="$NUMIMAGES"/>.jpg</xsl:attribute><xsl:variable
name="NUMIMAGES"
value="{$NUMIMAGES - 1}"/>
