[xsl] Grouping Using XSL

[Rigoberto <rbejaran@xxxxxxxxxxxx>]

hi everybody!!!

I got some problems grouping some data from a xml doc. Actually the xml 
doc looks like this:

<data>
      <col id="1">1</col>
      <col id="2">1</col>
      <col id="3">hello</col>
</data>
<data>
      <col id="1">1</col>
      <col id="2">1</col>
      <col id="3">bye</col>
</data>
<data>
      <col id="1">1</col>
      <col id="2">1</col>
      <col id="3">oops</col>
</data>
<data>
      <col id="1">1</col>
      <col id="2">2</col>
      <col id="3">hello</col>
</data>

what i´m trying to do, is create an xml document grouping the document 
source using the col elements dinamically ( col[1], col[1] and col[2], 
col[2],etc). so, if i use col[1] and col[2] the results should looks 
like this:

<data>
      <col id="1">1</col>
      <col id="2">1</col>
      <col id="3">
                  <val>hello</val>
                  <val>bye</val>
                  <val>oops</val>
      </col>
</data>
<data>
      <col id="1">1</col>
      <col id="2">2</col>
      <col id="3">
                  <val>hello</val>
      </col>
</data>

i´m using xalan(xalan-j_2_4_1) processor so I THINK (maybe i´m wrong) 
that i can´t use the <xsl:for-each-group/> tag. can i use any other 
processor? what can i do? any ideas?
i´m using jdk1.3.1.

thanks.
