RE: [xsl] sorting on data referenced with document()??

["Carter, Will" <WCarter at envestnetpmc dot com>]

hmm...

I figured that I would first try the extension function route, but I can't quite figure out how to get it working.  Excuse my ignorance, I am a xslt beginner and I have never added a.

anyway, I tried to first download the function itself:
http://www.exslt.org/exsl/functions/node-set/exsl.node-set.zip

but inside the zip, exsl.node-set.xsl isn't present.????

the only way I could get exsl.node-set.xsl in any manner is to download the all modules zip. 
http://www.exslt.org/all-exslt.zip
exsl.node-set.1.xsl and exsl.node-set.2.xsl are in that zip, so I am guessing that those are what I need.
I put these 2 xsl files in the same folder as my two.xsl

so I try to modify my stylesheet:
------------------------------------------------------
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:common="http://exslt.org/common"; xmlns="http://www.w3.org/tr/REC-html40"; version="1.0">
<xsl:import href="exsl.node-set.1.xsl" />
<xsl:import href="exsl.node-set.2.xsl" />
------------------------------------------------------

I add the variable as instructed (i hope this is right):
------------------------------------------------------
<xsl:variable name="persons">
   <xsl:for-each select="people/person">
     <xsl:copy>
       <xsl:copy-of select="@*"/>
       <xsl:copy-of select="*"/>
       <xsl:variable name="ownerName" select="@name"/>
       <xsl:for-each select="document('xml2.xml')">
         <xsl:copy-of select="key('turtleByOwner', $ownerName)"/>
       </xsl:for-each>
     </xsl:copy>
   </xsl:for-each>
</xsl:variable>
------------------------------------------------------

and I change the for each in the stylesheet to:
------------------------------------------------------
<xsl:for-each select="exsl:node-set($persons)/person">
------------------------------------------------------

I try to transform with xalan at my command line and I get:
------------------------------------------------------
java org.apache.xalan.xslt.Process -in xml1.xml -xsl two.xsl -out 2.html
file:///C:/xsl/two.xsl; Line 25; Column 57; XSLT Error (javax.xml.transform.Tran
sformerConfigurationException): javax.xml.transform.TransformerException: javax.
xml.transform.TransformerException: Prefix must resolve to a namespace: exslt
------------------------------------------------------

what am I doing wrong?

Hello Will,

you either have to statically change the context to the second document

<xsl:for-each select="document('xml2.xml')/people/person">
   <xsl:sort select="turtle"/>
   ...
</xsl:for-each>

(but I think that's not an option)

or you have to create a temporary tree with all information merged. You 
can do this either via a 2 transformations or using an extension 
function exslt:node-set(). While extension functions always have the 
disadvantage of less portability, exslt is an approach against that 
matter (http://www.exslt.org).

<xsl:variable name="persons">
   <xsl:for-each select="people/person">
     <xsl:copy>
       <xsl:copy-of select="@*"/>
       <xsl:copy-of select="*"/>
       <xsl:variable name="ownerName" select="@name"/>
       <xsl:for-each select="document('xml2.xml')">
         <xsl:copy-of select="key('turtleByOwner', $ownerName)"
       </xsl:for-each>
       <xsl:copy-of select="
     </xsl:copy>
   </xsl:for-each>
</xsl:variable>

<xsl:for-each select="exslt:node-set($persons)/person">
   <xsl:sort select="cat"/> <!-- or turtle -->
   ...
</xsl:for-each>

Other comments to your stylesheet:

Are you sure you want version="2.0"??
In the match attribute of the key, you don't need //. The key indexes 
the whole XML tree (so all turtle elements, even without //).

Regards,

Joerg
