XML Schema file to String

I want to get a XSD file containing a redefine element with another schemaLocation to a String, where the redefine is already handled (The string should represent the merged 2 XSD files). Is this even possible?

(I am using Xerces2-j --> java)

I am not able to generate an Document or valid string from a Schema:

SchemaFactory schemaFactory = 
  SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
Schema schemaXSD = schemaFactory.newSchema( new File ( "example.xsd" ) );

Or let the XML parser handle the redefine (This loads the redefine as a node without opening/loading the second file):

DocumentBuilderFactory parserFactory = DocumentBuilderFactory.newInstance();
parserFactory.setNamespaceAware(true);
DocumentBuilder parser = parserFactory.newDocumentBuilder();
return parser.parse(new File ( "example.xsd" ));

Let's see first if I can illustrate your question, based on what I understand it to be.

Say you have schema A.xsd:

<?xml version="1.0" encoding="utf-8" ?>
<!-- XML Schema generated by QTAssistant/XSD Module (http://www.paschidev.com) -->
<xsd:schema elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:complexType name="Base">
        <xsd:sequence>
            <xsd:element name="First"/>
        </xsd:sequence>
    </xsd:complexType>  
</xsd:schema>

And a redefining one (B redefines A):

<?xml version="1.0" encoding="utf-8"?>
<!--XML Schema generated by QTAssistant/XSR Module (http://www.paschidev.com)-->
<xsd:schema xmlns="[{no target namespace}]" attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="[{no target namespace}]" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:redefine schemaLocation="A.xsd">
        <xsd:complexType name="Base">
            <xsd:complexContent>
                <xsd:extension base="Base">
                    <xsd:sequence>
                        <xsd:element name="Second" minOccurs="0"/>
                    </xsd:sequence>
                </xsd:extension>
            </xsd:complexContent>
        </xsd:complexType>
    </xsd:redefine>
</xsd:schema>

My understanding of your saying a String, where the redefine is already handled (The string should represent the merged 2 XSD files) would be this one below:

<?xml version="1.0" encoding="utf-8"?>
<!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->
<xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:annotation>
        <xsd:documentation xmlns="">Generated from "Set1" under "Release1"</xsd:documentation>
    </xsd:annotation>
    <xsd:complexType name="Base">
        <xsd:sequence>
            <xsd:element name="First" type="xsd:anyType"/>
            <xsd:element minOccurs="0" name="Second" type="xsd:anyType"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>

If that's what you're asking, then I am not aware of any Java solution which would automatically do the requested refactoring. It is possible to do it; from what I know, you have to write the code yourself.

The only tool I am aware of, specifically designed to also cover your scenario, is the one I am associated with, but that runs on .NET only (recently it requires .NET 4.0 which puts Mono platforms out of reach).
