[xsl] problem: getting link text without document() function

["Trevor Nicholls trevor@xxxxxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hello

This list seems to have gone dormant but here goes

I have a working XSLT 1 stylesheet which determines the text to insert in
hyperlinks by identifying the linked elements in separate documents. I'm now
incorporating it into an application which uses Xopus to edit a source XML
document, and I have discovered that the stylesheet is only usable in IE.
Unfortunately it barfs in Chrome and Firefox, because whatever XSL processor
they use in those browsers does not support document(). The Xopus
documentation implies that whatever I am trying to achieve in this
stylesheet could be achieved using XIncludes (but they don't supply a useful
example for my requirement).

I have to concede that I was even less informed when I wrote this stylesheet
than I am now, so it may be horribly over-engineered and misguided - but at
least it has been working in IE (and in other contexts outside
Xopus-in-a-browser).

If anyone is able to direct me to a useful example, or provide some tips on
how to achieve what I am doing without using document(), I would be very
grateful.

Part of the stylesheet fragment follows:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";>

<!-- local key for cross references -->
<xsl:key name="link-id-key" match="*[@id]" use="@id" />

<!-- return the text that should be substituted in a link -->
<xsl:template name="link_text">
  <xsl:param name="linkurl" />

  <xsl:variable name="lt-file">
    <xsl:choose>
      <xsl:when test="contains($linkurl,'#')">
        <xsl:value-of select="substring-before($linkurl,'#')" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$linkurl" />
      </xsl:otherwise>
    </xsl:choose>
  </xsl:variable>

  <xsl:variable name="lt-id" select="substring-after($linkurl,'#')" />

<!-- file or anchor-in-file -->
  <xsl:choose>
    <xsl:when test="$lt-id = ''">
      <!-- FILE ONLY-->
      <xsl:variable name="candidate-text">
        <xsl:for-each select="document($lt-file,/)">
          <xsl:value-of select="normalize-space(./*/title)" />
        </xsl:for-each>
      </xsl:variable>
      <xsl:choose>
        <!-- can find the file -->
        <xsl:when test="$candidate-text != ''">
          <xsl:value-of select="$candidate-text" />
        </xsl:when>
        <!-- can't find the file -->
        <xsl:otherwise>
          <xsl:text>UNFOUND EXTERNAL DOCUMENT: </xsl:text>
          <xsl:value-of select="$linkurl" />
        </xsl:otherwise>
      </xsl:choose>
    </xsl:when>

    <xsl:otherwise>
      <!-- FILE#ID -->
      <xsl:variable name="simple-link">
        <xsl:for-each select="document($lt-file,/)">
          <xsl:value-of select="normalize-space(key('link-id-key',$lt-id))"
/>
        </xsl:for-each>
      </xsl:variable>
      <xsl:choose>
        <!-- can find the file -->
        <xsl:when test="$simple-link != ''">
          <xsl:value-of select="$simple-link" />
        </xsl:when>
        <!-- can't find the file -->
        <xsl:otherwise>
          <xsl:text>UNFOUND EXTERNAL REFERENCE: </xsl:text>
          <xsl:value-of select="$linkurl" />
        </xsl:otherwise>
      </xsl:choose>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>


By the way, can anyone tell me what has happened to Dave Pawson's invaluable
XSLT FAQ? I remember using it almost daily for a while and I feel a great
loss now that its seems to have vanished from the web

Thanks
