Subject: Re: [docbook-apps] column spanning issue


Well, it took some tracking, but I figured out that the issue arises because
I'm using Saxon 8 for the XSLT processor.

The culprit is the calculate.colspan template, scol and ecol, which
contains:

      <xsl:choose>
        <xsl:when test="$ecol &gt;= $scol">
          <xsl:value-of select="$ecol - $scol + 1"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="$scol - $ecol + 1"/>
        </xsl:otherwise>
      </xsl:choose>

It worked when I made the following change:

      <xsl:choose>
        <xsl:when test="number($ecol) &gt;= number($scol)">
          <xsl:value-of select="$ecol - $scol + 1"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="$scol - $ecol + 1"/>
        </xsl:otherwise>
      </xsl:choose>

Apparently, XSLT 2.0 (or perhaps just Saxon 8) has different rules for
converting strings to numbers. I'll post a message in the Saxon help list
and see what Mike Kay has to say. (Personally, I think the &gt;= operator
should imply conversion from strings to numbers, but perhaps there's some
bit of the spec that says otherwise.)

FWIW
