test grammar to reproduce bug (575 bytes, text/xml)

Description Lars Oppermann 2004-11-30 13:55:29 UTC 
try to validate a document against the attached grammar. xmllint reports a
violation of relaxng's list//ref constraint [1]. However, contraints are to be
checked after simplification (section 7 of [2]) and 4.19 in [relaxng] describes
how refs are resolved during simplification.

[1]: grammar.rng:17: element ref: Relax-NG parser error : Found forbidden
pattern list//ref
Relax-NG schema grammar.rng failed to compile

Comment 2 Daniel Veillard 2005-03-31 13:50:40 UTC 
Okay, fixed in CVS. I also  added the test to libxml2 regression suite,

  thanks !

Comment 3 Daniel Veillard 2005-09-05 08:59:35 UTC 
This should be closed by release of libxml2-2.6.21,

  thanks,

Daniel
Comment 4 Éric Bischoff 2006-11-28 18:16:31 UTC 
I can reproduce the problem with 2.6.27, with the attached test case.

This bug is annoying when validating Open Document files against the OASIS relax schema.
Comment 5 Daniel Veillard 2006-11-28 19:54:15 UTC 
Sorry can't reproduce, as I said it's part of libxml2 regression tests
test/relaxng/list.rng and test/relaxng/list_0.xml

paphio:~/XML -> xmllint --noout --relaxng test/relaxng/list.rng test/relaxng/list_0.xml 
test/relaxng/list_0.xml validates
paphio:~/XML -> xmllint --version
xmllint: using libxml version 20627-CVS2879

 Check your shared library paths, if the problem still exist provide a fully
reproduceable test case as a new bug, the one reported is fixed.

Comment 6 Éric Bischoff 2006-11-29 00:16:40 UTC 
Ooops!

"ldd xmllint" shows me that OpenOffice.org 2.0 provides an old copy of libxml2 that has the problem described in this bug report. Unfortunately, this version had precedence over my self-compiled version of libxml2.

I fixed the library loading order, and now it works. Still, OOo should ship with a more recent copy of libxml2.

I'm really sorry for the false alarm.
Comment 7 Daniel Veillard 2006-11-29 08:57:42 UTC 
No problem, that was easy to fix :-)
