Re: [docbook-apps] olinks to chapters in same book not working

That is very wierd.  This means the xsltproc serializer is producing
non-well formed output.  I've never seen that.  Exactly what version of
xsltproc are you using?

Subject: [docbook-apps] olinks to chapters in same book not working


I'm not sure whether this is a stylesheet problem or an xsltproc
problem.
Here's a quick summary:
 - DocBook 4.4, XSL Stylesheets 1.69.1
 - Modular book uses XInclude to pull in chapter files.
 - Using olinks for all cross references.
 - Using xsltproc and FOP 0.20.5 to generate FO and then PDF.
 - For each olink, xsltproc generates an opening fo:basic-link tag,
   and then, instead of closing the tag, it generates an empty one.
   When FOP encounters the empty one, it stops processing.
   Error: internal-destination or external-destination must be specified
in basic-link

Here are the (simplified) details:

>From the generated FO file:
--------------------------
See <fo:basic-link internal-destination="SysReq"> System
Requirements<fo:basic-link internal-destination="">


Sample olink from the ig/GettingStarted.xml file:
-----------------------------------
<para>
See <olink targetdoc="install" targetptr="SysReq" /> ...
</para>


>From the olinkdb-pdf.xml file:
-----------------------------
<dir name="docs">
<dir name="ig">
          <document targetdoc="install" >
       &igtargets;
          </document>
</dir>
</dir>

>From the command line (one line each command):
---------------------------------------------
xsltproc.exe --nonet --xinclude \
   --stringparam olink.debug 1 \
   --stringparam collect.xref.targets "only" \
   --stringparam targets.filename "targets.xml" \
   my-fo.xsl install_book.xml


xsltproc.exe --nonet --xinclude \
   --stringparam olink.debug 1 --output %src_root%\%fo_file%  \
   --stringparam target.database.document "olinkdb-pdf.xml"  \
   --stringparam current.docid "install" \
   my-fo.xsl install_book.xml

The file my-fo.xsl is a customization layer that imports
xsl/fo/docbook.xsl.
For what it's worth, olinks to chapters in other books work as expected.
For example, an olink from an Install Guide chapter to an Admin Guide
chapter
works, but an olink from one Install Guide chapter to another
Install Guide chapter fails as described above.

Thanks,
