XMLSchemaCollec tion Validation with xs:choice xs:any elements

[Matthew]

I have implemented the xmlSchemaCollec tion object to cache commonly
used schemas, as follows:

=============== =============== =============== =============== =============== ====

public void SchemaValidate( XmlDocument xmlDoc, string schemaURI,
string urnNamespace)
{
if (!m_SchemaColle ction.Contains( urnNamespace))
{
//add new schema to collection cache if appropriate
m_SchemaCollect ion.Add(urnName space,schemaURI );
}

//set up validating reader
XmlValidatingRe ader reader = new XmlValidatingRe ader(
xmlDoc.OuterXml ,
XmlNodeType.Doc ument,
null);

reader.Namespac es = true;
reader.Schemas. Add(m_SchemaCol lection);
reader.Validati onType = ValidationType. Schema;

ValidationEvent Handler EvtHandler = new
ValidationEvent Handler(this.Va lidationCallBac k);
reader.Validati onEventHandler += EvtHandler;

while (reader.Read())
{
//iterate entire document,buildi ng up XML Doc of ValidationError s
}
if (m_ValErrorsXml Doc.HasChildNod es)
{
#if DEBUG
m_ValErrorsXmlD oc.Save("C:\\te mp\\debug\\Sche maValidationErr ors.xml");
#endif
throw new Exception("Sche ma Validation Errors:" +
Environment.New Line + schemaURI + Environment.New Line +
m_ValErrorsXmlD oc.OuterXml);
}
}

=============== =============== =============== =============== =============== ====

The caching seems to work fine, but I get validation errors on xs:any
elements. The reader complains that elements contained are not
declared..
I suspect I will have problems with xs:choice elements too.

Using the validating reader without the schema collection, the input
validates OK .. ie. as follows:

=============== =============== =============== =============== =============== ====

public XmlDocument SchemaValidate( string XML, string RulesSchema)
{

XmlValidatingRe ader reader = new XmlValidatingRe ader(
XML,
XmlNodeType.Doc ument,
null);

XmlReader schemaReader = new XmlTextReader(R ulesSchema);

XmlSchema schema = XmlSchema.Read( schemaReader, new
ValidationEvent Handler(Validat ionCallBack));

reader.Schemas. Add(schema);

while (reader.Read())
{
//iterate entire document,buildi ng up XML Doc of ValidationError s
}

XmlDocument xml = new XmlDocument();

xml.Load(reader );
//xml.LoadXml(Rul esXML);

return xml;
}
=============== =============== =============== =============== =============== ====

I have a vague idea that this is related to serialization of the
cached schemas? but am just guessing. I have spent a day on this
already...

Any help would be much appreciated.

TIA

Caching the XmlSchemaCollec tion and using this for validation should be no
different than adding the schemas directly to the XmlValidatingRe ader except
for an improvement in performance.

Can you send the schema and the xml samples?

Thanks,

Thanks Priyal,

I sent some source code to the online.microsof t.com address. But the
address could not be resolved. So I used a plain microsoft.com address
which went through, but I am uncertain whether or not you actually
received the documentation? Could you confirm your address for me?

Thanks,
Matthew
