Error loading schema: a bug???

[ElleEmme]

I everybody,

when i try to load in a dataset an xml schema with ReadXmlSchema method, the
framework validator throws an error. The schema is divide in 3 files. The
main one "scheda_full.xsd" include the other "definizioni.xsd" and
"tipi_dati.xsd" which contain various definitions.

I try to validate the schema with many tools like xmlspy and it seems to be
valid.

If someone want to help me, I provide xsd files at

http://www.meo.it/schema_full.xsd
http://www.meo.it/DEFINIZIONI/definizioni.xsd
http://www.meo.it/DEFINIZIONI/tipi_dati.xsd

Thanks.

Could you quote the error message?

"An unhandled exception of type 'System.Data.DataException' occurred in
system.data.dll
Additional information: undefined type: 'str1'."

simpleType str1 is declared on third file (tipi_dati.xsd). It seems,
framework validator cannot see those declarations, but for sure it parse the
second and the third file!

Thanks in advance for your interest.

"Token" is a primitive Xml Schema type...
I am guessing that your namesapces are hooked up wrong. The "token" item
probably doesn't have "xs:" or "xsd:" before it?

I am having a similar problem. I receive the following error when attempting to use the ReadXmlSchema function on a DataSet:
An unhandled exception of type 'System.Data.DataException' occurred in system.data.dll
Additional information: Undefined data type: 'token'.

'token' is defined in a different xsd file that gets included (xsd:include) into the xsd file I pass into the ReadXmlSchema function.
Were you able to resolve this issue?

Thanks,

Thanks for the input. I noticed to that token is a derived/primitive type. I went through each XSD file that gets included into the the "main" XSD file. I didn't notice any areas where the "token" was being used without proper declaration.

For another experiment, I used the ReadXmlSchema DataSet function on each of the component XSD files. Each of them read into the DataSet just fine. It only gives me an error when I try to load the "main" XSD file that has all thee includes in it.

I'll keep researching the issue and let you know if I come up with anything.

Thanks for the help!!!
