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="$sortField/SortFields/SortField[1]/Sort"/> brings through the string
"lendername" I just can't see why the sorting is not working. Hard coding
the value "lendername" sorts the output perfectly so I'm sure that XSLT is
operating ok in all other repects.
From what I can tell the order, data-type and case-order work fine it's just
the select that doesn't do anything.
I have tried creating a variable to contain the <xsl:value-of
select="$sortField/SortFields/SortField[1]/Sort"/> but this has no effect. I
have tried a function to do the same but this also fails.
David Carlisle mentioned last time I asked this question the following:
"Ah, but there's the rub: is $sortField a document node (/) with child a
SortFields element, in which case $sortField/SortField[1] will select
nothing, or is it a SortFields element in which case $sortField/SortField[1]
will select something."
I don't really understand what the difference is here but guess that it
could be the root of my problems as $sortField is a document node.
Does anyone have any ideas?
Thanks in advance
Nick
