Re: Page number ranges

Thank you for your help Jeni. It gave some ideas on the logics involved, but
as I embed this code into my stylesheet there are no page numbers at all in
the output. Perhaps there is something in what I have written that conflicts
with the code you suggested, so I post the whole template here to see if you
or someone else can spot the problem.

  <xsl:template match="word">
    <!-- I put your variable here in the top. -->
    <xsl:variable name="entries" select="word[. = current()]" />
    <!-- This line is used because I don't want duplicate lines in the
         index for each match on the same word. -->
    <xsl:if test="not(.=preceding-sibling::word[1])">
      <fo:block xsl:use-attribute-sets="serif-10 hyphenation"
        text-align-last="justify">
        <!-- The word itself. -->
        <xsl:value-of select="."/>
        <!-- A space here, so that the line breaks before the leader
             if the numbers don't fit in the same line as the word. -->
        <xsl:text> </xsl:text>
        <fo:inline keep-together.within-line="always">
          <fo:leader leader-pattern="dots"/>
          <xsl:for-each select="$entries">
            <xsl:sort select="@page" data-type="number" />
            <xsl:choose>
              <xsl:when test="$entries/@page = @page - 1">
                <xsl:if test="not($entries/@page = @page + 1)">
                  <xsl:value-of select="concat('-', @page)" />
                </xsl:if>
              </xsl:when>
              <xsl:otherwise>
                <xsl:if test="position() != 1">, </xsl:if>
                <xsl:value-of select="@page" />
              </xsl:otherwise>
            </xsl:choose>
          </xsl:for-each>
        </fo:inline>
      </fo:block>
    </xsl:if>
  </xsl:template>

"12-13" is good, but I wonder what happens if there are matches on page 12,
13, 14 and 15? Will they be written "12-14, 15" or "12-15"?
