A good guide to XML Schema is Priscilla Walmsley's book Definitive XML
Schema published by Prentice Hall.
It's probably overkill to learn all about XML Schema just for this problem,
but I mentioned it because there are hundreds of errors that people make
with path expressions which would be diagnosed much more quickly if people
used schema-aware stylesheets and queries. Of course, you still need to
understand the XSLT/XPath rules to get things right.
I still think the right solution for this problem might be to generate the
stylesheet before running it. You said that wasn't possible, but you didn't
say why.

Hi,
thanks for info, unfortunatly I don't know how to make a
schema... at the risk of being off topic does anyone have any
good references to get me started?
cheers

<xsl:param name="sortField"/>
And into this param i pass the XML:
<SortFields>
<SortField>
<Sort>lendername</Sort>
<Order>ascending</Order>
<DataType>text</DataType>
<CaseOrder>lowercasefirst</CaseOrder>
</SortField>
</SortFields>
rather than use 12 parameters (four for each <xsl:sort/>),
I had hoped
that using this XML I would be able to read the values out like so:
<xsl:sort select="$sortField/SortField[1]/Sort"
order="{$sortField/SortField[1]/Order}"/>
You want $sortField/SortFields/SortField[1]/Order
As far as I can tell the order attribute should read
"acsending" out
of the XML but I've no real way of finding out what it is reading.
Take a look at the trace() function, or simply do
<xsl:copy-of select="$sortField"/>.
Better still, write a little schema for this XML document and
make your stylesheet schema-aware, and then the error will be
reported to you at compile time.
