Re: rearranging and colouring a document

Hello,
thanks for your advice, I managed to get the sorting to work. It
took a while, as the fast sablotron seems to have problems with
the solution, but xalan works find for me.

However, I tried the proposed solution for colouring, but had
problems, as my description of the source was imprecise. Here a
more suitable example:

<text>
<sp><speaker>foo</speaker><p>text 1</p></sp>
<sp><speaker>bar</speaker><p>text 2</p></sp>
<sp><speaker>foo</speaker><p>text 3</p></sp>
<sp><speaker>xxxx</speaker><p>text 4</p></sp>
<sp><speaker>foo</speaker><p>text 5</p></sp>
<sp><speaker>xxxx</speaker><p>text 6</p></sp>
<sp><speaker>bar</speaker><p>text 7</p></sp>
</text>

how could I extract some kind of index from the speaker element?
- that is in this example:
foo: 1
bar: 2
xxxx: 3
(or any other unique number sequence suitable for indexing).

So it can be mapped to colours, which for example can be found in
an external xml document.

Thanks,

Horst
