Fw: Intelligent ulink for PDF generated files

Dear members,

 

When I generates my document into PDF format every time I have on my document <ulink>, like this:

 

<ulink url="http://www.eclipse.org">Eclipse</ulink>

 

I get:

 

Eclipse[www.eclipse.org]

 

but if I refers many times to Eclipse on the same paragraph, I get the same output information, so it doesn't detect that on this paragraph was referenced Eclipse once, so it is not necessary to informs about the URL all the time.

 

My idea is to allow the user configurate this behaviour, the following strategies could be implemented:

- Reference once per paragraph or,

- Reference once per page or,

- Reference once per section or,

- Reference once per chapter or,

- Reference once per document

 

This is my suggestion, but I don't know how to implement it, my XSL level is poor, but probably some of you have thought about this problem before than me.

 

Thanks in advance,

 

On the files xref.xsl there is the following information about ulink, so I think it should be the starting point:

 

==============================================

<xsl:template match="ulink" name="ulink">
  <fo:basic-link xsl:use-attribute-sets="xref.properties">
    <xsl:attribute name="external-destination">
      <xsl:call-template name="fo-external-image">

      </xsl:when>
      <xsl:otherwise>
        <xsl:apply-templates/>
      </xsl:otherwise>
    </xsl:choose>
  </fo:basic-link>

  <xsl:if test="count(child::node()) != 0
                and string(.) != @url
                and $ulink.show != 0">
    <!-- yes, show the URI -->

      <xsl:when test="$ulink.footnotes != 0 and not(ancestor::footnote)">

        <fo:inline

          <xsl:call-template name="hyphenate-url">

          <xsl:text>]</xsl:text>
        </fo:inline>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:if>
</xsl:template>

 

 

 

<xsl:template name="ulink.footnote.number">

      <xsl:number level="any"
 
                  from="chapter|appendix|preface|article|refentry|bibliography[not(parent::article)]" 
                  count="footnote[not(@label)][not(ancestor::tgroup)]|ulink[node()][@url != .][not(ancestor::footnote)]" 
                  format="1"/>
    </xsl:variable>
    <xsl:choose>
      <xsl:when test="string-length($footnote.number.symbols) &gt;= $fnum">
        <xsl:value-of select="substring($footnote.number.symbols, $fnum, 1)"/>
      </xsl:when>
     
 <xsl:otherwise>
        <xsl:number value="$fnum" format="{$footnote.number.format}"/>
      </xsl:otherwise>
    </xsl:choose>

</xsl:template>
