类名以父节点的类名为前缀：使用xsd.exe从XML生成CS代码

Question

I am trying to generate a C# file from a XML file using xsd.exe. I am facing a problem that every class is prefixed with the class name of its parent node. So it is generating very long names, depending on the depth of an XML element. I am posting a sample.
Sample.xml

<?xml version="1.0" encoding="UTF-8"?>
<A attrib1="100">
    <B attrib2="200">
        <C attrib3="300" />
    </B>
</A>    

On submitting xsd Sample.xml command I get Sample.xsd as below:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
  <xs:element name="A">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="B" minOccurs="0" maxOccurs="unbounded">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="C" minOccurs="0" maxOccurs="unbounded">
                <xs:complexType>
                  <xs:attribute name="attrib3" type="xs:string" />
                </xs:complexType>
              </xs:element>
            </xs:sequence>
            <xs:attribute name="attrib2" type="xs:string" />
          </xs:complexType>
        </xs:element>
      </xs:sequence>
      <xs:attribute name="attrib1" type="xs:string" />
    </xs:complexType>
  </xs:element>
  <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element ref="A" />
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

On submitting xsd sample.xsd /classes command I get Sample.cs as following:

        set {

        }
    }
}

The problem is it is producing classes AB and ABC , which are being used in class A and class AB respectively. This is creating very long names in real scenario. Is there a way to suppress this behavior, so that I get classes as A, B and C , instead of A, AB and ABC ? Please use my example as reference.

Answer 1

You need to give names and definitions to all your complex types explicitly in the schema and then reference these types when defining the elements. The XSD.exe tool will work with these "type" names as class names. An example is shown for A. You need to break out all complex types similarly in the schema.

<xs:element name="A" type="AType"/>

<xs:complexType name="AType">
    <xs:sequence>
        <xs:element name="B" type="BType" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
    <xs:attribute name="attrib1" type="xs:string"/>
</xs:complexType>
