Why is XSD.EXE creating two .XSD files and how to use them?

Question

I use the following command to generate the linked xsd file from my input XML file - response.xml, my confusion: (1) why are there two outputs from the xsd file (response.xsd and response_app1.xsd), I think there should be only one of them? (2) If I need to generate a C # class file using xsd / classes, which xsd file should I use?

My environment: VSTS 2008 + C # + .Net 3.5.

D:\>xsd response.xml Microsoft (R) Xml Schemas/DataTypes support utility [Microsoft (R) .NET Framework, Version 2.0.50727.3038] Copyright (C) Microsoft Corporation. All rights reserved. Writing file 'D:\response.xsd'. 

Here is my input XML file and Ouput XSD files,

EDIT 1:

when I execute xsd response.xsd to create a related C # class, error messages appear and here is the detailed output,

 D:\>xsd response.xsd /classes Microsoft (R) Xml Schemas/DataTypes support utility [Microsoft (R) .NET Framework, Version 2.0.50727.3038] Copyright (C) Microsoft Corporation. All rights reserved. Schema validation warning: The 'http://www.mycorp.com/Order/2009/05/mex:Items' e lement is not declared. Line 10, position 16. Warning: Schema could not be validated. Class generation may fail or may produce incorrect results. Error: Error generating classes for schema 'response'. - The element 'http://www.mycorp.com/Order/2009/05/mex:Items' is missing. If you would like more help, please type "xsd /?". 

thanks in advance George

Answer 1

George,

To generate classes from these files, you must specify both on the command line:

 D:\>xsd response.xsd response_app1.xsd /classes 

---

It has already been correctly said that the two .xsd files are related to the fact that there were two XML namespaces in the original XML file. By the way, I have a little guess because you did not publish the XML file.

Answer 2

The reason two files are generated is because your XML contains two XML namespaces; each generated XSD corresponds to a namespace. The one that imports the namespace mycorp for the soap shell namespace (which you can see from the xs: import element).

Answer 3

IIRC, you use both, one probably refers to the other.

Answer 4

Yes, remove the namespaces from the XML file and generate it, you will get one XSD file
