RE: DOCBOOK-APPS: Recursive Reference in XML DTD ??

[Stuart Farnan <st...@neoworks.com>]

Andi,

Thanks a lot for the help, have tried v1.1.3 of xerces and the problem seems
to go away. I guess that means its a bug in v1.2.0.

Not sure if this is a registered bug, but if not, the details are listed
below.

Thanks guys,

Stuart

Hi,
	I had the same problem on Windows platform. It took me some days to
solve
it. Try to use an older (or the newest version if corrected the error)
version of xerces, for example xerces v1.1.3. This version didn't give me
this error. It seems to me a problem with  xerces.

Hi,

I am having a problem which I describe in detail below, after seeing the
traffic over the last day or so I guess this question is more appropriate on
this mailing list than on the xerces-j list.  Any help anyone could give me
would be greatly appreciated.

I am using:

JDK for Linux (build 1.3.0beta_refresh-b09)
xerces-j v1.2.0

The XML file that is causing problems is listed below.  It references the
public DocBook DTD, which I have not listed here, but is accessible in the
location shown below.  The java code I am running is shown below also.

The class shown compiles fine.  I run it with the command:

$ java SAXWriter ../xml/simplefruitbowl.xml

The out put I get is as follows:

$ java SAXWriter ../xml/simplefruitbowl.xml
Parsing file: ../xml/simplefruitbowl.xml ...
Parse error: Recursive reference "%dbnotn;". (Reference path:
(top-level)-%dbhier;-%dbnotn;-%dbnotn;)
Done

I took a look at the DTD, and the files it includes, and I cant work out why
it thinks there is a recursive reference?  Is this a bug with the parser?
Or am I using it incorrectly?

Thanks in advance.

Stuart
