Description

When using the Saxon TraceListener I get different output from xsl:on-non-empty compared to when not using the TraceListener. Test case on-non-empty-008.xsl shows the issue:

<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
  <out>   
    <xsl:for-each select="/*/thing">
      <item><xsl:value-of select="name()"/></item>
    </xsl:for-each>
    <xsl:on-non-empty>
      <p>There are some things</p>
    </xsl:on-non-empty>  
  </out>
</xsl:template>
</xsl:stylesheet>

The data is:

<doc> <item>a</item> <item>b</item> <item>c</item> </doc>

Without the TraceListener configured the result is:

<out/>

With the TraceListener configured the result is:

<out>
<p>There are some things</p>
</out>

With the TraceListener and default optimisation setting I also get the message SXWN9029.

With the TraceListener and no optimisation, -opt:0, I don't get the message SXWN9029 but do still get the wrong output.
