RE: [xsl] Is it possible to create xsl:sort from input parameters using XSLT 2.0 (Saxon)?

[Nick Glenister <NGlenister@xxxxxxxxxxxxxxxx>]

Hi,

Sorry to bring this problem up again but I'm still having problems with
getting this sort to work.

To recap I have an XSLT that transforms XML into ASP.NET which shows a list
of financial products and some basic details. In order to sort these
products I am passing in a second XML document node in the following format:

<SortFields>
	<SortField>
		<Sort>lendername</Sort>
		<Order>ascending</Order>
		<DataType>text</DataType>
		<CaseOrder>lower-first</CaseOrder>
	</SortField>
	<SortField>
		<Sort>lenderid</Sort>
		<Order>ascending</Order>
		<DataType>text</DataType>
		<CaseOrder>lower-first</CaseOrder>
	</SortField>
	<SortField>
		<Sort>productid</Sort>
		<Order>ascending</Order>
		<DataType>text</DataType>
		<CaseOrder>lower-first</CaseOrder>
	</SortField>
</SortFields>


This xml is passed into this parameter:

<xsl:param name="sortField" as="document-node()"/>

This XML document defines three levels of sorting and is applied to the
primary XML using the following XSLT (separated over several lines for
clarity in the e-mail. There is one of these sort elements for each of the
three sorts):

<xsl:sort select="$sortField/SortFields/SortField[1]/Sort"
order="{$sortField/SortFields/SortField[1]/Order}" 
data-type="{$sortField/SortFields/SortField[1]/DataType}" 
case-order="{$sortField/SortFields/SortField[1]/CaseOrder}" />


The problem is that it doesn't work. There are no errors but the sorting
does not occur. Doing a <xsl:value-of
select="$sortField/SortFields/SortField[1]/Sort"/> brings through the string
"lendername" I just can't see why the sorting is not working. Hard coding
the value "lendername" sorts the output perfectly so I'm sure that XSLT is
operating ok in all other repects.
