Question : Why does this xslt sort not work?

HI,

I have an XSLT that was succesfully sorting an xml file I had created by hand.  However, now I am manipulating the XML in code (C#, Net framework 3.5), and when I apply the XSLT transformation, the sort no longer works.  I suspect its something to do with the encoding Im using (?).  Can anyone shed any light?

the XML:

<ROOT ID="1" TYPE="TUTORIAL" TITLE="Darren test tutorial" IMAGE="./images/TUTORIAL.gif"

POSITION="0"><ITEM ID="2" TYPE="TOPIC" TITLE="Topic 2" IMAGE="./images/TOPIC.gif"

POSITION="1"></ITEM><ITEM ID="1" TYPE="TOPIC" TITLE="Topic 1" IMAGE="./images/TOPIC.gif"

POSITION="0"><ITEM ID="1" TYPE="PAGE" TITLE="New Page" IMAGE="./images/PAGE.gif"

POSITION="0"></ITEM><ITEM ID="1" TYPE="QPAGE" TITLE="A Question" IMAGE="./images/QPAGE.gif"

POSITION="1"></ITEM></ITEM></ROOT>

The XSLT:

<?xml version="1.0" encoding="utf-16"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

      <xsl:template match="ROOT">
        <ROOT>
              <xsl:attribute name="ID">
                    <xsl:value-of select="@ID"/>
              </xsl:attribute>
              <xsl:attribute name="TYPE">
                    <xsl:value-of select="@TYPE"/>
              </xsl:attribute>
              <xsl:attribute name="TITLE">
                    <xsl:value-of select="@TITLE"/>
              </xsl:attribute>
              <xsl:attribute name="IMAGE">
                    <xsl:value-of select="@IMAGE"/>
              </xsl:attribute>
              <xsl:attribute name="POSITION">
                    <xsl:value-of select="@POSITION"/>
              </xsl:attribute>

              <xsl:apply-templates mode="getItems" >
                    <xsl:sort select="@position" data-type="number" order="ascending"/>
              </xsl:apply-templates>
             
            
        </ROOT>
  </xsl:template>

      <xsl:template match="ITEM" mode="getItems">
            <ITEM>
                  <xsl:attribute name="ID">
                        <xsl:value-of select="@ID"/>
                  </xsl:attribute>
                  <xsl:attribute name="TYPE">
                        <xsl:value-of select="@TYPE"/>
                  </xsl:attribute>
                  <xsl:attribute name="TITLE">
                        <xsl:value-of select="@TITLE"/>
                  </xsl:attribute>
                  <xsl:attribute name="IMAGE">
                        <xsl:value-of select="@IMAGE"/>
                  </xsl:attribute>
                  <xsl:attribute name="POSITION">
                        <xsl:value-of select="@POSITION"/>
                  </xsl:attribute>
                  
                  <xsl:apply-templates mode="getItems" >
                        <xsl:sort select="@position" data-type="number" order="ascending"/>
                  </xsl:apply-templates>
            </ITEM>
      </xsl:template>
      

</xsl:stylesheet>

Answer : Why does this xslt sort not work?

XSLT is case-sensitive language. Since the attribute POSITION is uppercased in the XML it should be uppercased in the XSLT:
<xsl:sort select="@POSITION" data-type="number" order="ascending"/>
