How to define multiple elements in XML Schema with the same name and different attribute value allow
- by David Skyba
I would like to create XML Schema for this chunk of xml, I would like to restrict the values of "name" attribute, so that in output document on and only one instance of day is allowed for each week day:
<a>
<day name="monday" />
<day name="tuesday" />
<day name="wednesday" />
</a>
I have tried to use this:
<xs:complexType name="a">
<xs:sequence>
<xs:element name="day" minOccurs="1" maxOccurs="1">
<xs:complexType>
<xs:attribute name="name" use="required">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="monday" />
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:complexType>
</xs:element>
<xs:element name="day" minOccurs="1" maxOccurs="1">
<xs:complexType>
<xs:attribute name="name" use="required">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="tuesday" />
</xs:restriction>
</xs:simpleType>
</xs:attribute>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
but XML Schema validator in eclipse says error "Multiple elements with name 'day', with different types, appear in the model group.".
Is there any other way?
