XSL Copy Problem

[ajc308]

I'm attempting to sort the <file>s within each <directory> in my XML according to their file extension, then write out the resulting sorted data back to XML format. I had it working before, and when I opened up the file the next day, the XSL behaved completely different. I don't know if I accidentally changed something, but I can't see any problems with my code.

My Sample XML:

<root name="PlanRepository">
  <directory name="connoraj">
    <directory name="single_run.dat.07-23-2007.10-59-51">
      <file>insidebox.txt</file>
      <file>outsidebox.txt</file>
      <directory name="SAFE_Input">
        <file>leapseconds.txt</file>
        <file>single_run.dat</file>
        <directory name="LeoInputs">
          <file>control_earth.txt</file>
          <file>leo_sc_prop2.txt</file>
        </directory>
      </directory>
      <directory name="SAFE_Output">
        <file>single_run.aer.dat</file>
        <file>single_run.control_files</file>
        <file>single_run.dv.dat</file>
        <file>single_run.est_pv.dat</file>
        <file>single_run.host_ephem.e</file>
        <file>single_run.host_inertial.dat</file>
        <file>single_run.residuals.dat</file>
        <file>single_run.tar_ephem.e</file>
        <file>single_run.tar_inertial.dat</file>
        <file>single_run.true_pv.dat</file>
      </directory>
    </directory>
  </directory>
</root>

My XSL File:

<xsl:template match="root">
    <xsl:copy>
      <xsl:attribute name="name">PlanRepository</xsl:attribute>
      <xsl:apply-templates/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="directory">
    <xsl:copy>
      <xsl:copy-of select="@name"/>
      <xsl:choose>
        <xsl:when test="@name = 'SAFE_Output'">
          <xsl:for-each select="file">
            <xsl:sort select="substring-after(substring-after(.,'.'),'.')" />
            <xsl:copy-of select="."/>
          </xsl:for-each>
        </xsl:when>
        <xsl:otherwise>
          <xsl:for-each select="file">
            <xsl:sort select="substring-after(.,'.')" />
            <xsl:copy-of select="."/>
          </xsl:for-each>
        </xsl:otherwise>
      </xsl:choose>
      <xsl:apply-templates select="directory"/>
    </xsl:copy>
  </xsl:template>

My resulting output:

insidebox.txtoutsidebox.txtsingle_run.datleapseconds.txtcontrol_earth.txtleo_sc_prop2.txtsingle_run.control_filessingle_run.aer.datsingle_run.dv.datsingle_run.est_pv.datsingle_run.host_inertial.datsingle_run.residuals.datsingle_run.tar_inertial.datsingle_run.true_pv.datsingle_run.host_ephem.esingle_run.tar_ephem.e

My desired output XML (<file>s are sorted by file extension):

<root name="PlanRepository">
  <directory name="connoraj">
    <directory name="single_run.dat.07-23-2007.10-59-51">

      <directory name="SAFE_Input">
        <file>single_run.dat</file>
        <file>leapseconds.txt</file>
        <directory name="LeoInputs">
          <file>control_earth.txt</file>
          <file>leo_sc_prop2.txt</file>
        </directory>
      </directory>
      <directory name="SAFE_Output">
        <file>single_run.control_files</file> 
        <file>single_run.aer.dat</file>        
        <file>single_run.dv.dat</file>
        <file>single_run.est_pv.dat</file>        
        <file>single_run.host_inertial.dat</file>
        <file>single_run.residuals.dat</file>
        <file>single_run.tar_inertial.dat</file>
        <file>single_run.true_pv.dat</file>
        <file>single_run.host_ephem.e</file>
        <file>single_run.tar_ephem.e</file>        
      </directory>
    </directory>
  </directory>
</root>

Can anyone help me out with this problem?

Thanks,
Andrew

For some reason or another, you're not hitting your root template.
Check to make sure that you don't have any xmlns: attribute in your source xml, and that root is spelled with the same capitalization in both your source xml and your xslt.
