RE: summing up incrementally

Where's the summing? Please tell us your method of computing the values to be 
placed in the output tree element's "percentage-increase" attributes.

Subject:  [xsl] summing up incrementally

Is there a way to sum up incrementally?

My source tree looks something like this:

<root>

<year year = "1937">

  <month month = "January" percentage-increase = "105"/>
  <!--and so on for each month-->
  <month month = "December" percentage-increase = "103"/>
</year>

<year year = "1938">
  <month month = "January" percentage-increase = "104"/>
  <!--and so on for each month-->
  <month month = "December" percentage-increase = "102"/>
</year>


<year year = "1939">
  <month month = "January" percentage-increase = "106"/>
  <!--and so on for each month-->
  <month month = "December" percentage-increase = "108"/>
</year>

</root>

I need to sum up the percentage-increase just for December. I want my
resulting tree to look like this:

<root>

<year year = "1937" percentage-increase = "103"/>

<!--now add up Decmber 1937 and December 1938-->
<year year = "1938" percentage-increase = "105"/>


<!--now add up Decmber 1937, December 1938, and December 1939-->
<year year = "1938" percentage-increase = "113"/>

</root>

I'm thinking I can do with is a recursive template, but can't figure out
how.

Thanks

Paul
