Subject: Re: [docbook-apps] xml:base problem with nested XIncludes
Hi Ron, I'm not able to duplicate this problem. I'm using your files with Oxygen 10.3, DocBook XSL 1.75.1, Saxon 6 and XEP 4.13, Java 1.6.0_05. Two things: 1. I didn't see where you described the directory structure containing your files. As far as I can tell, they all reside in the the current directory, except the graphic which is in a subdirectory named 'images'. Is that correct? I wasn't clear what you expected the src attribute in the fo file to be, as compared to what you got. 2. Normally the XInclude processor does not add xml:base unless an included file is in a different directory, and that doesn't seem to be the case here. I'm wondering where the full path information came from, because it does not appear to be in the XML files. Normally a processor will work with relative paths, but the error message indicates a full path. Is a catalog involved here?
