[Mono-list] Validation of XML

Hi All...

I need to validate an Xml content and I have two ways:

* Using DTD file.
* Using XSD schema file.

The problem is that i have a DTD file that it's ok, work fine with
xmllint validation program. but my implementation with DTD Validation
don't work with mono. I decide to work with XSD validation schema and
work fine for me. Now i can validate a xml  against XSD schema file
very well with mono.

But here it's the new problem... when i generate a XSD schema file
from XML using xsd.exe this generate a wrong XSD Schema file.


Now the 2 ways...  (1) how i can generate a valid XSD schema file from
Xml (not manual) or (2) how i can validate a Xml using valid DTD file?

I attached the source files that I'm still working

The error using DTD validation:

$ mono -V
Mono JIT compiler version 1.1.8.2, (C) 2002-2005 Novell, Inc and
Contributors. www.mono-project.com
        TLS:           __thread
        GC:            Included Boehm (with typed GC)
        SIGSEGV      : normal
        Globalization: norma

$ mcs --version
Mono C# compiler version 1.1.8.0

$ mono ValidateXml.exe DTD activities.dtd activities.xml

Unhandled Exception: System.Xml.XmlException: Unexpected declaration
