Hi Nick,
As far as I can tell, it is not possible to generate <xsl:sort>
instructions that way, since the <xsl:sort>s in your example would only
apply to your inner for-each loop.
Is a two-pass solution also suitable for you?
best regards,
Roman

Subject: [xsl] Is it possible to create xsl:sort from input
parameters using XSLT 2.0 (Saxon)?
Hi,
I am trying to create dynamic sorts in my XSLT file so the
end user can select different fields to sort the data on then
rerun the XSLT.
The XSLT is called from a vb.net app where the chosen sort
fields are passed as XML into a param called sortField:
<SortFields>
<SortField DataType="number" CaseOrder="lowercasefirst"
Order="ascending">lenderid</SortField>
<SortField DataType="number" CaseOrder="lowercasefirst"
Order="ascending">generalproductid</SortField>
</SortFields>
Using the following XSL:
<xsl:for-each select="$tempRoot/product">
<xsl:choose>
<xsl:when test="boolean($sortField)=true">
<xsl:for-each
select="$sortField/SortFields/SortField">
<xsl:sort select="."
order="@Order"
data-type="@DataType" case-order="@CaseOrder" />
</xsl:for-each>
</xsl:when>
</xsl:choose>
</xsl:for-each>
which (in my head at least) would result in something akin too:
<xsl:for-each select="$tempRoot/product">
<xsl:sort select="lenderid" order="ascending"
data-type="number" case-order="lowercasefirst"/>
<xsl:sort select="generalproductid" order="ascending"
data-type="number" case-order="lowercasefirst"/>
</xsl:for-each>
The main input XML document which is being transformed looks
like this:
<root>
<product>
<lenderid>1234</lenderid>
<generalproductid>12344321</genrealproductid>
<lendername>fred</lendername>
...
</product>
<product>
...
</product>
</root>
Having tried doing it I'm now pretty sure that this isn't
possible as I get a compile error on the xsl:sort order as it
is expecting ascending or descending.
Is there any other way of achieving this?
Cheers
Nick
