Re: [xsl] Getting specific elements from a list

[JBryant@xxxxxxxxx]

Hi, Joe,

The thing that's tripping you up is that the EnumValueDescription elements 
don't share the same context, so [1] and [last()] don't do what you want. 
The trick is to get them into the same context, which I did with a 
variable in the following stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text"/>

  <xsl:variable name="EVDs" select="//EnumValueDescription"/>

  <xsl:template match="tblEnumeratedTypes">
    test (
          int,
          <xsl:value-of select="EnumeratedType"/>,
          <xsl:value-of select="$EVDs[1]"/>,
          <xsl:value-of select="$EVDs[last()]"/>
    );
  </xsl:template>
 
</xsl:stylesheet>

The output (with Saxon 8.4):

    test (
          int,
          ColorType,
          Red,
          Blue
    );
 
You could do it with a key, too, and I'm sure there are yet other ways 
(but variable and key came to mind right off).

[xsl] Getting specific elements from a list







Hi, I have the following XML snippit :

<tblEnumeratedTypes>
                 <EnumeratedType>ColorType</EnumeratedType>
                 <tblEnumValues>
 <EnumeratedType>ColorType</EnumeratedType>
 <EnumValueDescription>Red</EnumValueDescription>
                 </tblEnumValues>
                 <tblEnumValues>
 <EnumeratedType>ColorType</EnumeratedType>
 <EnumValueDescription>White</EnumValueDescription>
                 </tblEnumValues>
                 <tblEnumValues>
 <EnumeratedType>ColorType</EnumeratedType>
 <EnumValueDescription>Blue</EnumValueDescription>
                 </tblEnumValues>
</tblEnumeratedTypes>

What I need as output is 

TEST ( int, ColorType, Red, Blue )

The problem I'm having is getting the Red and Blue, basically, the 
First and last EnumeratedType element of EnumeratedTypes.

I tried various combinations, although it seems this should have
worked...

                 <xsl:template match="tblEnumeratedTypes_WC" 
mode="range-macro">


test ( 
                 int, 
                 <xsl:value-of select="EnumeratedType"/>,
                 <xsl:value-of select=".//EnumValueDescription[1]"/>,
                 <xsl:value-of select=".//EnumValueDescription[last()]"/>
) ;

                 </xsl:template>

When I execute that I get (line breaks are not a problem)

TEST ( 
                 int, 
                 ColorType,
                 Red,
                 Red
                 ) ;

What is the problem is that I can never get the last Value to be Blue.

Oh, XSL Procesor : Microsoft (R) XSLT Processor Version 4.0
Also tried it using Mozilla, same result

Any Ideas ?

TIA
