> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
> elementFormDefault="qualified" xmlns="http://www.example.org/schema/";
> targetNamespace="http://www.example.org/schema/";>
> <xs:element name="root">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="item">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="foo"
> type="xs:string"></xs:element>
> <xs:element name="bar"
> type="xs:string"></xs:element>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> </xs:schema>
> Compile and run commands:
> javac -cp .;./xercesImpl.jar ValidationTest.java
> java -cp .;./xercesImpl.jar ValidationTest
> Result:
> ValidationTest start
> declaration==null //1
> declaration==null //3
> declaration==null //4
> When the element is other than document element there is no information about
> this element declaration. Using document or documentElement to construct
> DOMSource and DOMResult makes it works fine.
