[xsd-users] Problem: About targetNamespace

[杨开锦]

I use the xsd.exe to generate xxx.hxx and xxx.cxx for my xxx.xsd

but when I try to parse the xml file, it failed with: no declaration found for element 'xxx'.


I try to locate the problem, and it seems to be that, my xxx.xsd has a targetNamespace declaration.


I take the situation into the Hello World Example:


xsd:


<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema_instance"
           targetNamespace="http://www.w3.org/2001/XMLSchema_instance"
           elementFormDefault="qualified" attributeFormDefault="unqualified">


  <xs:complexType name="hello_t">
    <xs:sequence>
      <xs:element name="greeting" type="xs:string"/>
      <xs:element name="name" type="xs:string" maxOccurs="unbounded"/>
    </xs:sequence>
  </xs:complexType>


  <xs:element name="hello" type="xsi:hello_t"/>


</xs:schema>



xml:


<?xml version="1.0"?>
<hello xmlns:xsi="http://www.w3.org/2001/XMLSchema_instance"
       xsi:noNamespaceSchemaLocation="hello.xsd">


  <greeting>Hello</greeting>


  <name>sun</name>
  <name>moon</name>
  <name>world</name>


</hello>





Then it does not work well, I need to known if there is some way to come through.


Note:
When I put the xsi prefix before the hello, greeting, name in the xml file, it stay still.
My xsd file comes from a third part, and it is long enough, so it would be large work to change all the declarations in the xsd file to kill the targetNamespace.
