Hi Wendell,
The syntax <xsl:value-of
select="count(preceding::item[category=current()/category])+1"/>
when placed at <!-- ?? --> in my XSL, produces
numbering 1,2,1,2 and not 1,2,3,4 !
I am also interested to know how the numbering
(1,2,3,4 ..) can be produced using
- a 2 pass solution
- using node-set extension
Regards,
Mukul

In the general case, two passes, or a resort to a
node-set extension
function, is necessary for a clean solution to this,
because the numbering
depends not on the order and position of nodes in
the source document, but
in the result.
When we are not reordering the nodes within their
groups, however, one can
often force this ...
<xsl:value-of
select="count(preceding::item[category=current()/category])+1"/>
but be warned: it can be slowish to execute on large
documents.
No variable reassignment is called for here.
Cheers,
Wendell
James's spec:
I have the following format but am having trouble
trying to group items
(in html) under one common category so that it isnt
repeated for every
item but can act as a title:
<rss version="0.92">
- <channel>
- <item>
<title>title here</title>
<category>Top Stories</category>
<link>http</link>
<description>text is heredescription>
</item>
</channel>
<item>
<title>title here</title>
<category>top stories</category>
<link>http</link>
<description>text is heredescription>
</item>
</channel>
<item>
<title>title here</title>
<category>Stories today</category>
<link>http</link>
<description>text is heredescription>
</item>
</channel>
<item>
<title>title here</title>
<category>Stories today</category>
<link>http</link>
<description>text is heredescription>
</item>
</channel>
</rss>
e.g. the final look i wanted to create was:
<h1>top stories </h1>
ITEM1 <xsl:value-of select="description">
ITEM2 <xsl:value-of select="description">
<h1>stories today</h1>
ITEM3 <xsl:value-of select="description">
ITEM4 <xsl:value-of select="description">
