[opencms-dev] XML-Content xsd:choice

[Thomas Göttlich]

Hi Patric,

thanks for the advice.

Does that mean I have to use an intermediate schema to define the choice?

Currently, I have this:

test.xsd    //my example below shows the complexType definition
module1.xsd  //a simple opencms schema to define a sub-module
module2.xsd  //another simple opencms schema to define a sub-module

So what I want to do is to have a list of "modules" (or elements) in the
test files where the modules can be of one of those two types.

Creating another complextType in the test.xsd schema like the following,
results in the error "Exactly 2 complex type definitions are required, not
3."

 <!-- 3. Root element name and type of our XML type -->
  <xsd:element name="Tests" type="OpenCmsTests"/>

  <!-- 4. Definition of the type described above -->
  <xsd:complexType name="OpenCmsTests">
    <xsd:sequence>
      <xsd:element name="Test" type="OpenCmsTest"
        minOccurs="0" maxOccurs="unbounded"/>
    </xsd:sequence>
  </xsd:complexType>

  <!-- 5. Data field definitions -->
  <xsd:complexType name="OpenCmsTest">
    <xsd:sequence>
      <!--
        <xsd:element name="MT1" type="OpenCmsModule1" minOccurs="0" />
        <xsd:element name="MT2" type="OpenCmsModule2" minOccurs="0"  />
       -->
       <xsd:element name="Text" type="OpenCmsText"
          minOccurs="0"/>
    </xsd:sequence>

    <!-- 6. locale attribute is required -->
    <xsd:attribute name="language" type="OpenCmsLocale"
      use="optional"/>
  </xsd:complexType>

  <xsd:complexType name="OpenCmsText">
    <xsd:choice>
      <xsd:element name="Headline" type="OpenCmsString" minOccurs="0" />
       <xsd:element name="Title" type="OpenCmsString" minOccurs="0" />
    </xsd:choice>

    <xsd:attribute name="language" type="OpenCmsLocale" use="optional"/>
  </xsd:complexType>

Note that the names are just arbitrary chosen, in order to do some tests.

Should the structure instead be like this?

test.xsd    //this would contain a list of the type defined by
modulechoice.xsd
modulechoice.xsd //would only contain the element with the xsd:choice
between the modules
module1.xsd  //a simple opencms schema to define a sub-module
module2.xsd  //another simple opencms schema to define a sub-module


Thanks for your effort.

Thomas
