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 >= $scol"> <xsl:value-of select="$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) >= 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 >= operator should imply conversion from strings to numbers, but perhaps there's some bit of the spec that says otherwise.)
