[gobo-eiffel-develop] More on line numbering

[Colin P. A. <co...@co...>]

The following ought to give some clues about line numbering:

An XSLT trace fragment:

       <instruction element="param" name="title" line="18" base_uri="file:///home/colin/gobo/test/xml/xslt/schematron/schematron-basic.xsl">
       </instruction><!-- param -->
       <instruction element="param" name="contents" line="19"
       base_uri="file:///home/colin/gobo/test/xml/xslt/schematron/schematron-basic.xsl">


And here follows the schematron-basic.xsl file:

<?xml version="1.0" ?>
<!-- Basic metastylesheet for the Schematron XML Schema Language.

<!-- Schematron basic -->

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

<xsl:import href="skeleton1-5.xsl"/>

<xsl:template name="process-prolog">
   <axsl:output method="text" />
</xsl:template>

<xsl:template name="process-root">
   <xsl:param name="title" />
   <xsl:param name="contents" />
   <xsl:value-of select="$title" />
   <xsl:text>&#10;</xsl:text>
   <xsl:copy-of select="$contents" />
</xsl:template>

<!-- use default rule for process-pattern: ignore name and see -->
<!-- use default rule for process-name: output name -->
<!-- use default rule for process-assert and process-report:
     call process-message -->

<xsl:template name="process-message">
   <xsl:param name="pattern" />
   <xsl:param name="role" />
   <xsl:text>In pattern </xsl:text>
   <xsl:value-of select="$pattern" />
   <xsl:if test="$role">
      <xsl:text> (</xsl:text>
      <xsl:value-of select="$role" />
      <xsl:text>)</xsl:text>
   </xsl:if>:
   <xsl:apply-templates mode="text" />
   <xsl:text>&#10;</xsl:text>
</xsl:template>

</xsl:stylesheet>

Note that the title and contents xsl:params are on lines 40 and 41
respectively, whereas they are reported on lines 18 and 19.

Not the large comment starts on line 2 and ends on line 24 (counting
the xml declaration as line 1). So it spans 23 lines. That is, 22 more
than might be expected.

Now 18 + 22 = 40, so I think there is a (and maybe the only) source of
error in line counting.
