There's an XML message I have, that has no namespace information.
Then there is a XSD schema that is must validate against, but this has a
targetNamespace and xmlns of "http://www.wbf.org/xml/b2mml-v02".
How do I get this XML to validate against the Schema in C#?
If I use XmlSpy (2005 home edition) to perform the validation, it first
inserts namespace and schema information into the XML before validating.
Validation then seems to work if I take this modified XML and push it
through my code, only problem is none of my XSL mappings now work because
they don't include any namespace information!
---------------------------------------------------------------------------
I've listed the relevant code below:
I've got the XML:
<?xml version="1.0" encoding="UTF-8"?>
<ProductionSche dule>
<Location>
<EquipmentID>09 45</EquipmentID>
<EquipmentEleme ntLevel>Site</EquipmentElemen tLevel>
</Location>
<PublishedDate> 2004-12-08T13:20:27.804 </PublishedDate>
<ProductionRequ est>
<ID>00001000237 7</ID>
<SegmentRequire ment>
<ID>10000000000 0002689</ID>
<globe_SegmentS tate>Finished</globe_SegmentSt ate>
</SegmentRequirem ent>
</ProductionReque st>
</ProductionSched ule>
Which must be validated against the XSD:
<?xml version="1.0" encoding="UTF-8"?>

The C# code I'm currently using (which isn't validating) is as follows:
public class XsdValidation
{
/// <summary>
/// Validation Error Count
/// </summary>
static int errorCount = 0;
/// <summary>
/// Validation Error Message
/// </summary>
static string errorMessage = "";
/// <summary>
/// Validate the XML string against the XSD file
/// </summary>
/// <param name="xsdPath"> </param>
/// <param name="xmlDoc"></param>
public void Validate(string xsdPath, string xmlDoc)
{
// only validate if a file has been specified
if ( xsdPath == "" )
{
return;
}
// if the file doesn't exist, this is a problem we need to
report.
// This will stop the message being processed, preventing any
messages
// that may be invalid from passing through BIF
if ( !File.Exists ( xsdPath ) )
{
throw new Exception("The Schema Validation file
'"+xsdPath+" ' does not exist.");
}
// Declare local objects
XmlTextReader tr = null;
XmlSchemaCollec tion xsc = null;
XmlValidatingRe ader vr = null;
// Text reader object
tr = new XmlTextReader(x sdPath);
xsc = new XmlSchemaCollec tion();
xsc.Add(null, tr);
// XML validator object
vr = new XmlValidatingRe ader( xmlDoc, XmlNodeType.Doc ument,
null);
vr.Schemas.Add( xsc);
// Add validation event handler
vr.ValidationTy pe = ValidationType. Schema;
vr.ValidationEv entHandler +=
new ValidationEvent Handler(Validat ionHandler);
// Validate XML data, if there's a problem the
// event is fired and errorMessage is constructed
while(vr.Read() );
vr.Close();
// Raise exception, if XML validation fails
if (errorCount > 0)
{
string reportedErrorMe ssage = errorMessage;
errorCount = 0;
errorMessage = "";
throw new Exception("XML Message Validation Failed:\r\n" +
reportedErrorMe ssage);
}
}
/// <summary>

static void ValidationHandl er(object sender,
ValidationEvent Args args)

errorCount ++;
}
}
