Re: [xslt] Error on identity transform

["Schubert, Aaron" <aschubert rightnow com>]

Well you are not seeing the issue because I mistakenly wrote that the error occurred when calling xsltParseStylesheetFile when the error actually occurs in xsltApplyStylesheet.  The problem occurs when I call the Options template from within the DesignModel template after already outputting the Options node.  The Options template then is to basically output all attributes unless one of the more specific templates match and specifically do not copy the attribute to the result as these have been phased out.  I have included the relevant xsl, input xml, and a snippet of what the result used to look like.

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

   <xsl:variable name="Modified">false</xsl:variable>
   <xsl:variable name="no_button">NoButton</xsl:variable>
   <xsl:variable name="newline">
     <xsl:text>

 </xsl:text>
   </xsl:variable>

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*" />
    </xsl:copy>
  </xsl:template>

  <xsl:template match="DesignModel">
    <DesignModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
      <xsl:value-of select="$newline" />

      <Pages>
        <xsl:value-of select="$newline" />
        <xsl:apply-templates select="Pages/SurveyPageModel" />
        <xsl:value-of select="$newline" />
      </Pages>

      <xsl:value-of select="$newline" />

      <Options>
        <xsl:value-of select="$newline" />
        <xsl:apply-templates select="Options" />
      </Options>
      <xsl:value-of select="$newline" />
    </DesignModel>

  </xsl:template>
.
.
.

<!-- Need to remove the button text attributes from the options xml -->

  <xsl:template match="Options">
    <xsl:apply-templates select="node()|@*"/>
  </xsl:template>

  <xsl:template match="//DesignModel/Options/@NextPageButtonText">
  </xsl:template>

  <xsl:template match="//DesignModel/Options/@FinalPageButtonText">
  </xsl:template>

</xsl:stylesheet>

----------------------------------------------------------
A very much stripped down version of the input xml file looks like the following:

<DesignModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
  <Pages>
    <SurveyPageModel Title="Page 1" DocumentId="26">
      <Items>
      </Items>
    </SurveyPageModel>
  </Pages>
  <Options FinalPageOption="NoButtons" FinalPageRedirectUrl="" ProgressBarVisible="false" ProgressBackColorDone="AAAAAA" 
ProgressBackColorCurrent="000000" ProgressBackColorRemainder="FFFFFF" ProgressBorderColor="000000" NextPageButtonText="Next" 
FinalPageButtonText="Submit">
    <FinalActions/>
  </Options>
</DesignModel>

----------------------------------------------------------

This is what the options xml should end up looking like. Notice, the NextPageButonText and FinalPageButtonText have been removed.  This worked with the old libraries but causes the error mentioned before with the current ones.

<Options FinalPageOption=\"NoButtons\" FinalPageRedirectUrl=\"\" ProgressBarVisible=\"false\" ProgressBackColorDone=\"AAAAAA\" ProgressBackColorCurrent=\"000000\" ProgressBackColorRemainder=\"FFFFFF\" ProgressBorderColor=\"000000\">\n\n    <FinalActions/>\n  </Options>

I don't see the problem you're reporting:

libxslt 10122 was compiled against libxml 20629
