Re: relative path from one node to another (XSLT 2.0 solution)

Hi, Richard,

I did it this way:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <!-- process the root -->
  <xsl:template match="document">
    <xsl:result-document href="root/delete.me"/>
    <xsl:apply-templates>
      <xsl:with-param name="path" select="'root'"/>
    </xsl:apply-templates>
  </xsl:template>

  <!-- process the directories -->
  <xsl:template match="section[section/@display='page']">
    <xsl:param name="path"/>
    <xsl:result-document href="{concat($path, '/', @id, '/delete.me')}"/>
    <xsl:apply-templates>
      <xsl:with-param name="path" select="concat($path, '/', @id)"/>
    </xsl:apply-templates>
  </xsl:template>

  <!-- process the pages -->
  <xsl:template 
match="section[(_at_)display='page'][not(section/@display='page')]">
    <xsl:param name="path"/>
    <xsl:result-document href="{concat($path, '/', @id, '.xml')}">
      <chunks>
        <xsl:apply-templates/>
      </chunks>
    </xsl:result-document>
  </xsl:template>

  <!-- process the inline sections -->
  <xsl:template match="section[(_at_)display='inline']">
    <content chunk="{(_at_)id}"/>
  </xsl:template>

</xsl:stylesheet>

Note that the "delete.me" bit is in there because I couldn't quickly 
figure out how to get result-document to make just a directory. Perhaps 
folks who have more file-system experience (or more time to fiddle) can 
help there.

Also, I relied on the fact that, in the data you presented, directories 
always had child sections with display="page" attributes. You'll have to 
tinker with the algorithm a bit if that's not true in your production 
system.

Anyway, when I applied this stylesheet to your data, I got the desired 
output, except that I got no temporary directory because your data didn't 
specify one. I did get a file called staff/permanent.xml, though. Perhaps 
you have a small error from copying earlier chunks into your sample. I 
didn't create actual HTML files, so I just called them XML files. I'm sure 
you can adjust when you fill out the details.

Interesting problem, by the way.

Tested with Saxon 8.4.
