为什么XSD.EXE创建两个.XSD文件，以及如何使用它们？

Question

I am using the following command to generate related xsd file from my input XML file -- response.xml, my confusion is (1) why there are two xsd file output (response.xsd and response_app1.xsd), I think there should be only one of them generated? (2) If I need to generate C# class file by 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]

Writing file 'D:\response.xsd'.

Here is my input XML file and ouput XSD files,

EDIT 1:

when I execute xsd response.xsd to generate related C# class, there are error messages, and here are 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 list 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 because there were two XML namespaces in your original XML file. BTW, I'm guessing a little here because you did not post the XML file.

Answer 2

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

Answer 3

IIRC，你使用两者，一个可能会引用另一个。

Answer 4

是的，从XML文件中删除命名空间并生成它，您将获得单个XSD文件
