Re: [xml] Strange validation errors in libxml 2.9.0 with MSVC 2010

Hi Daniel,
thanks for responding over the weekend, much obliged.

Please note that the problem is not the system ID; I replaced the full path to the relative one as I was sure that my full path would not work for anyone else.

So, the DTD is in fact, found - how else would xmllint.exe be able to validate it? I messed up the DTD on purpose once just to see if there are errors - and there were, so xmllint can find the DTD for sure.

The source of my frustrations are the validation errors that are produced by a seemingly correct code, validated and well-formed XML and DTD.

The only thing I can think of is that the some build setting may be wrong - however I am not adept enough to discover that.

Did anyone managed to get xmlReaderForFile(...) working on MSVC 2010 without validation errors?

Best regards: Zoltán Ördögh

  See your xml and the system identifier you use for the DTD

  file:///./

if I use that I get an error that the DTD fails to be loaded on linux
and validation fails (xml and dtd being in the same directory) switching
to
  ./testme.dtd

works after that i.e. xmllint code succeeds

file:// URIs are (or used to be) completely underspecified, and
what you use there would mean on a Linux machine, the file testme.dtd
which is in the . directory under to root of the filesystem of the
localhost machine, i.e. /testme.dtd instead of ./testme.dtd
What is does on Windows and why, I can't guess and I can't test,
simply run your program under a debugger, since you have a reliable
behaviour !

Daniel
