[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Realising when you hit the last match?
 Hit a bit of a problem... Just can't seem to figure out when I am processing the last match. Okay, goes a bit like this: XML sample (please forgive the syntax, hopefully it paints a clear enough picture): <heading class='2001'>
<heading class='2003'>
<heading class='2000'>
</heading>
</heading class>
<heading class='2000'>
<heading class='2003'>
<heading class='2000'>
</heading>
</heading>
</heading>
</heading>Now, what I want to do is to find all headings that either have a class of '2000' or have a class of '2003'. Then I would like to process them all together and when I hit the last one do something special. Exactly what I want to do is to output the class value when a '2000' or '2003' is matched. But I would like them seperated with a comma. This means that when I hit the last one I do not want to whack out a comma. Okay... sounds simple right? It did to me too... Until I realized that there might not be any '2000' or there might not be any '2003'. The problem is then even more prominent when you consider that I am actually dealing with about 10 different class values. I have just done two here to give an example. I am doing something like this: <xsl:apply-templates select="//pdxc2:heading[@class='2000'] | //pdxc2:heading[@class='2003'] | //pdxc2:heading[@class='2008'] | //pdxc2:heading[@class='2009']"/> So I am only interested in '2000', '2003', '2008' and '2009'. As I said there may be multiples or even none of each class, so I can't guarantee that the last match of a class '2009' will be the last one to deal with. I then have a template match for each class which then deals with the output. This is where I get stuck. I have no idea how to know when I have hit the last match which could be any of the classes above. I am trying to get an output like this(according to the sample xml above): 2003, 2000, 2000, 2003, 2000 Notice no comma on the end. Don't know about all of you, but aren't commas in these situations always an a issue in any language!? Ahhhhhh Help! Thanks for any advice! Aaron McGrath.
