RE: Retaining value of a Global variable

Hi,
I'll post it soon. I am trying to find simpler solution. Michael had suggested
position() but since I may have the article(s) at any position, that would not
work. I am trying with xsl:key.

My main problem is:
I have an XML that contains multiple articles for a newsletter. There could or
could not be some articles with article-classification as 'Webcasts'. If I
find even a single article with classification of 'Webcast', then I want to
print a title 'Webcasts' and then list all the articles. I have done the code
for listing the articles. The problem I am having is identifying if there's
even one article of that classification and then print 'Webcast' title only
once. That's why I was looking to set the global variable and then increment
it once I hit the first webcast article and then go for listing the articles
of that type. But it seems that's not possible. Therefore I am trying xsl:key.
Any other input on doing it simpler way?

The XML sample:
<article>
   <class>News</class>
   <teaser>AAAAAAAAAA</teaser>
</article>
<article>
   <class>Webcast</class>
   <teaser>BBBBBBBBBB </teaser>
</article>
<article>
   <class>News</class>
   <teaser>CCCCCCCCCCC </teaser>
</article>
<article>
   <class>Webcast</class>
   <teaser>DDDDDDDD </teaser>
</article>

Thanks
Vivek

I'm going to leave this one aside for a bit. Until we hear again from
Vivek, it's not clear to me that this is -- quite -- a standard grouping
problem, due to the requirement to group according to string containment,
not just string equality.

It'd be much easier if we could see a representative example of the input.
Vivek, could you post a bit of it, along with a restatement of what kind of
output you want for your input? That way it's all in one email -- less to
guess, less confusing to track.

On the other hand, maybe our haphazard comments and hints have been enough
to help Vivek find the solution on his own.

Cheers,
Wendell
