Re: opposite of preceding-sibling

Hi Jan,

To answer your subject-line's question, the opposite of
preceding-sibling is following-sibling.

It's hard to tell because I can't see how the source XML you gave tied
up with the result that you were after, but I think that this is a
grouping problem. You want to group the index elements by the artnr
element they're associated with in a particular row.

So index the row elements by artnr:

<xsl:key name="row-by-artnr" match="row" use="artnr" />

That means that if you do:

  key('row-by-artnr', 'gh')

you'll get all the row elements whose child artnr element has the
value 'gh'.

Then it looks as though you want to create a col element for each
unique artnr, with an artnr element inside with a nummer attribute
holding the value of the artnr from the original XML. You can do this
with:

  <xsl:for-each select="/test/result/row
                          [count(.|key('row-by-artnr', artnr)[1]) =
                           1]">
    <col>
      <artnr nummer="{artnr}">
        ...
      </artnr>
    </col>
  </xsl:for-each>

Within the artnr element, you want to add copies of all the index
elements from the row elements with that value for the artnr element.
You can retrieve those with the key:

  <xsl:for-each select="/test/result/row
                          [count(.|key('row-by-artnr', artnr)[1]) =
                           1]">
    <col>
      <artnr nummer="{artnr}">
        <xsl:copy-of select="key('row-by-artnr', artnr)/index" />
      </artnr>
    </col>
  </xsl:for-each>

Of course you could use templates rather than xsl:for-each if you
prefer.

I hope that helps,

Jeni
