Re: [docbook-apps] Aligning numbers in table cells with xsl

Thanks Bob for the tip about translate. I finally worked it out -
    coding as follows:

              <xsl:choose>

                <xsl:when test="contains(., '&lt;')">

                  <xsl:value-of select="(translate(., '&lt;', ''))" />

                </xsl:when>

                <xsl:when test="contains(., '&gt;')">

                  <xsl:value-of select="(translate(., '&gt;', ''))" />

                </xsl:when>

            <!--margin
        and indent for portrait format tables-->    

            <xsl:choose>

              <xsl:when test="(ancestor-or-self::d:table/@tabstyle = 'numbers'
        or 

             
        ancestor-or-self::d:table/@tabstyle = 'numberstripe') and
        not(ancestor::d:thead or

              ancestor::d:tfoot)
and
        preceding-sibling::d:entry and
        ((string(number($stringanglesymbol)) !=
        'NaN') or (string(number(.)) != 'NaN'))">

                <xsl:attribute name="text-align">right</xsl:attribute> <!--text

        right margin as a percentage of cell width (default: 30)-->

                <xsl:attribute name="margin-right">

                  <xsl:choose>

                    <xsl:when test="self::d:entry/d:footnote"> <!--reduce the right margin if

                  there
        is a
        footnote in the cell-->

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

                    </xsl:when>

                    <xsl:otherwise>

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

                    </xsl:otherwise>

                  </xsl:choose>

One way to handle those
          characters is to use the translate() function to remove them
          before doing the test.  If the third argument of translate()
          is empty, then the matching characters in the second argument
          disappear, and all other characters are left untouched. 
          Something like:

      
 

      
string(number(translate(.,
          '&lt;&gt;', '')))

          Aligning numbers in table cells with xsl

        

        

        I managed to (almost) fix the problem by adding a test for NaN
        to the string variable:

        

        <xsl:if test="(ancestor-or-self::d:table/@tabstyle =
        'numbers' or 

              ancestor-or-self::d:table/@tabstyle = 'numberstripe') and
        not(ancestor::d:thead or

              ancestor::d:tfoot) and preceding-sibling::d:entry and
        (string(number(.) != 'NaN'))">

        

        This however will not select any cells that have a number and
        a non-numeric string (such as greater than or less than signs:
        <1, or >20) - my test treats those cells as a string and
        not as a number. I now need to find how to convert &lt; and
        &gt; to a number so that the test selects cells with a
        number and a lt or gt sign.
