Hi Chris, Btw, I ran across a potentially better answer to your question (depending on the behavior of your xslt processor): http://www.dpawson.co.uk/xsl/sect2/N2602.html#d3859e19

Ant then checks to make sure all are the images available and kills with a useful error message the build if any are missing. To avoid an annoying build/fail/fix/repeat cycle, the error message shows all missing images rather than only listing the first missing image it finds. I think to do something like this within the xslt would require that you write an extension/call out to java.

It might go something like this: <mediaobject> <imageobject> <xi:include fileref="../../images/coding-cycle.png"> <xi:fallback>Image file is unavailable.</xi:fallback> </xi:include> </imageobject> </mediaobject> You would need to use a DTD or schema (or at least a DTD fragment) that allows for use of xinclude. I hope this helps, Jim
