Hi,

I am getting following error, when I try to run XSD.exe for a schema.

  - Error generating code for DataSet ''.
  - Unable to convert input xml file content to a DataSet. Undefined data type:
'token'.
  - Undefined data type: 'token'.

Can you please suggest what needs to be done to generate the class file for that schema?

I am looking for: 1) Other tool like XSD.exe which works fine. or 2) how to resolve the above error message for XSD.exe

It sounds as if your schema is incorrect. Have you tried validating it with an XML Schema for XML Schemas?

The schema is given by government agency. Hence we can safely assume it be to be correct.

OK, may I ask what schema it is or is that confidential? It is just that the word "token" is not defined, yet in schemas there is a construct called "#token" and it might just be that the # is missing.

I can share the file - no problem with that. Only thing is I am unable to upload it even after zipping it as it does not seem to allow XSD file.  Do you know better way to share that file for you to see?

OK, I have looked at the schema and it is correct. The use of xs:token (A string that does not contain line feeds, carriage returns, tabs, leading or trailing spaces, or multiple spaces) is in fact in XML Schema 2001, but it seems that xsd.exe does not support it.

I have found this entry :-

http://bytes.com/groups/net-xml/177628-error-using-derived-simpletype-attribute-xsd-dataset

which reports the same problem. There he substituted xs:string for xs:token.  That's a work around for the moment.

I suggest that you download the latest .Net development set, since the problem might be resolved, although I can find no reference on the Microsoft site. This codeproject page shows the status of the various binders, which if you can't temporarily change the schema to get started, might help you to pick another tool. It is definitely a bug in xsd.exe.
