Re: schema validation : choice with min/maxOccurs in group not allow ?

[K. Venugopal]

Hi,

Code says :

       // Neither minOccurs nor maxOccurs may be specified
       // for the child of a model group definition.
may be one of the developers can help you by pointing  to the spec.

you could use this until then .

<xs:group name="myGroup">
   <xs:sequence>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
          <xs:element name="one" type="xs:string" />
          <xs:element name="two" type="xs:string" />
      </xs:choice>
   </xs:sequence>
  </xs:group>

Thanks

hi,

I have a problem of XML schema validation with Xerces 2.4.0. it seems that the inclusion of an element 'choice' with the attributs minOccurs and/or maxOccurs into a element 'group' was not allow by xerces. Whereas it validates with XMLSpy and some exemples are built this way in specifications.

Here's an example to see my problem :

The XML schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Fiche">
<xs:complexType>
<xs:sequence>
<xs:group ref="myGroup"/>
</xs:complexType>
</xs:element>
<xs:group name="myGroup">
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="one" type="xs:string" minOccurs="0"/>
<xs:element name="two"type="xs:string" minOccurs="0"/>
</xs:choice>
</xs:group>
</xs:schema>

or

<xs:group name="myGroup">
<!--xs:choice minOccurs="0" maxOccurs="unbounded"-->
<xs:sequence>
<xs:element name="one" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="two" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:group>

Thanks

The XML file :

<?xml version="1.0" encoding="UTF-8"?>
<Fiche xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="test.xsd">
<one>blabla</one>
<one>blabla bla</one>
<two>bla</two>
</Fiche>

My command line :
java -cp xercesImpl.jar;xercesSamples.jar;xml-apis.jar;xmlParserAPIs.jar sax.Counter -s test.xml

and the result :
[Error] test.xsd:11:27: s4s-att-not-allowed: Attribute 'minOccurs' cannot appear in element 'choice'.
[Error] test.xsd:11:27: s4s-att-not-allowed: Attribute 'maxOccurs' cannot appear in element 'choice'.

Best regards
