I have configured XEP to use an XML catalog, not for image
locations but to use a local SVG DTD when processing images that reference such
a DTD. I edited the xep.bat batch file (I'm running on Windows) to add two
items to the java CLASSPATH:
directory containing the CatalogManager.properties file, that
points to an xml catalog file.
Then you add these options to the java command line in that
When first setting up a catalog, I usually set verbosity=4 in
the CatalogManager.properties file so I can see how the catalog file is being
used during the process. Then set it back to 1 when everything is

We have a manual that consists of several XML files containing the
chapters, and a main XML file that just uses XInclude to "collect" the chapters.
All XML files are located in the same folder (in this case called "en/"). In
this folder, there is also an "images" folder that contains all the images
included in the manual (using <imagedata
fileref="images/image_file_name.pdf"). Generating a PDF for the manual works
fine, as long as all referred images are present in the "images" folder.
When we translate the manual we send all the (english) XML files to the
translators, and for each language we get back a set of XML files with the
"readable" content translated but everything else unchanged - file names, xml:id
attributes, and fileref attributes for images. The images seldom contains
anything that needs to be translated, and if they do we take care of that
ourselves. When generating PDF:s for the translated manuals, we currently
have to copy the entire "images" folder from the "en" folder to each
folder with the translated manuals, and then make sure that we correctly replace
the few translated images.
Now, what I hoped would be possible with XML catalogs was to get the XSL-FO
renderer to look for the images in multiple locations:
- First look in the "images" folder in the folder with the current XML
- if the image file was not found there, look in the "en/images"
This way we would not have to fill the "images" folder for each translation
with identical copies of the un-translated images, and instead keep only one
copy in the "en/images" folder. It would also be easier to check that all images
that need translation are actually translated, since the "images" folder for the
translated manual would only contain translated images.
So far I have tried using both XEP (that we currently use for generating
PDFs) and FOP (as an experiment), and xsltproc, Saxon (6.5.5) and Xalan for
generating the FO files, but nothing has worked for me. I must have tried every
trick I could find on the interwebs on how to get these tools to resolve using
XML catalogs, but have this far only managed to get xsltproc to resolve the
XIncludes in the main XML file (but never Saxon or Xalan).
