Using Xerces-J 2.4.0 with Namespaces in Schema

Hi All,

         I'm dom.Writer from the DOM samples and I'm trouble with Namespaces
in a Schema. For example if this is my XML file:

 

<?xml version = "1.0" ?>

<cust:Customer xmlns:cust = "http://www.example.org/Customers"

               xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

               xsi:schemaLocation = "Customers.xsd">

   <FirstName>Ray</FirstName>

   <MiddleInitial>G</MiddleInitial>

   <cust:LastName>Bayliss</cust:LastName>

</cust:Customer>

 

This is my Schema called Customers.xsd

 

<?xml version = "1.0" ?> 

<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"

           targetNamespace = "http://www.example.org/Customers"

           xmlns = "http://www.example.org/Customers">

 

   <xs:element name = "Customer" >

      <xs:complexType>

         <xs:sequence>

            <xs:element name = "FirstName" type = "xs:string" />

            <xs:element name = "MiddleInitial" type = "xs:string" />

            <xs:element ref = "LastName" />

         </xs:sequence>

      </xs:complexType>

   </xs:element>

 

   <xs:element name = "LastName" type = "xs:string" />

 

</xs:schema>

 

Using the dom.Writer with this command -v for validation -s for Schema
validation

java dom.Writer -v -s CustomerA.xml > CustomerA-result.xml

 

I get the following errors:

 

 [Warning] CustomerA.xml:4:53: SchemaLocation: schemaLocation value =
'Customers.xsd' must have even number of URIs.

[Error] CustomerA.xml:4:53: cvc-elt.1: Cannot find the declaration of
element 'cust:Customer'.

 

The Questions I have are:

1) It cannot find the Customers.xsd the corresponding Schema for the file -
why?

 

2) It cannot find the Customers.xsd file - why?

 

3) How do I get multiple namespaces working for the Schema and the XML file?

 

 

Thnaks Marco.

  Hi Marco ,

schemaLocation needs namespace name and location of the schema , so you 
need to modify your xml file as
xsi:schemaLocation = "http://www.example.org/Customers Customers.xsd">

An example from net is below:

   xsi:schemaLocation=
     "http://contoso.com/People 
      http://contoso.com/schemas/people.xsd 
      http://contoso.com/schemas/Vehicles
      http://contoso.com/schemas/vehicles.xsd
      http://contoso.com/schemas/People
      http://contoso.com/schemas/people.xsd">

Regards
venu
