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

[Zoltán Ördögh (GMail) <csimbi gmail com>]

Hi all,
I've been using libxml 2.7.7 in the past with BCB6 and it was working fine.
Now I use libxml 2.9.0 with MSVC 2010 (_MSC_VER = 1600) and I get strange validation errors when I try to read the file back that I wrote out before.

I am getting a bit frustrated because I am using the exact same code as I did in BCB6 and despite all my efforts, it always fails.
When I validate the XML with a third-party tool, it all checks out just fine.
When I run: "xmllint.exe --valid testme.xml", it simply dumps the XML back without any validation errors.

For some reason, libxml 2.9.0 on MSVC 2010 won't validate it (even though it's from the same build as xmllint.exe itself).

This is the code that opens the file:

#include "libxml/xmlreader.h"
.
.
.
m_pxmlTextReader=xmlReaderForFile(sXML.c_str(), NULL, XML_PARSE_COMPACT | XML_PARSE_BIG_LINES | XML_PARSE_DTDVALID);

if(m_pxmlTextReader)
{
    if(xmlTextReaderRead(m_pxmlTextReader)==1 && xmlTextReaderIsValid(m_pxmlTextReader)==1)
    {
        // processing
    }
...


"// processing" is never reached due to the validation errors.

I attached a simple XML with the DTD that can be used to test it in case you're willing to give it a go.
I captured the errors I see in output.txt, please find it attached.
As you can see from the output, the DTD is found but for some reason, libxml can't match it vs. the XML file.

I don't think it's relevant but this is the libxml config that I use at the moment:

Config command:
cscript configure.js iconv=no static=yes debug=yes compiler=msvc prefix=..\..\..\libxml2

Build commands:
call "C:\Program Files (x86)\MSVS10\VC\vcvarsall.bat"
nmake /f Makefile.msvc
nmake /f Makefile.msvc install

Config output:

Microsoft (R) Windows Script Host Version 5.8

libxml2 version: 2.9.0
Created Makefile.
Created config.h.
