Subject: Re: [docbook-apps] Different values for footer.column.widths on first page and rest of document?


Hi,
It is not possible to do what you want with just stylesheet parameters.  You would 
need to copy the template named 'footer.table' from fo/pagesetup.xsl to your 
customization layer and customize it.  In that template, you will find three calls to 
the template named 'header.footer.width', which is a utility template that extracts 
one of the three number values from the 'footer.column.widths' parameter.

In your customization, you would use an xsl:choose statement to override the numbers 
for your special case.  The 'footer.table' template has three params of its own that 
are populated when it is called.  The template param named 'sequence' will contain a 
value of 'first', 'odd', 'even', or 'blank', depending on the current page.  For 
example, for the first column, use:

<fo:table-column column-number="1">
  <xsl:attribute name="column-width">
    <xsl:choose>
      <xsl:when test="$sequence = 'first'">
        <xsl:text>0</xsl:text>
      <xsl:when>
      <xsl:otherwise>
        <xsl:call-template name="header.footer.width">
          ...
        </xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:attribute>
</fo:table-column>

Do similar overrides for the other two columns.

The reason you cannot just customize the utility template 'header.footer.width' is 
because it is not passed the 'sequence' param, although it probably should be to 
enable such customization.
