Hello,

I am trying to replace an element from one schema(source) to another
schema(target) schema using DOM APIs as below :
and the replacement is not happening properly.

------------------------------------------------------------ --
TestContentCopy.java
------------------------------------------------------------ --
package test.schema;

import java.io.File;
import java.io.IOException;
import java.util.Collection;
import java.util.Collections;

import org.eclipse.emf.common.util.URI;

import org.eclipse.xsd.XSDSchema;
import org.eclipse.xsd.util.XSDResourceImpl;
import org.w3c.dom.Element;
import org.w3c.dom.Node;

public class TestContentCopy implements IObjectActionDelegate {

public void setActivePart(IAction action, IWorkbenchPart targetPart) {
}

public void run(IAction action) {

String sourceLoc = "C:\\test1.xsd";
String targetLoc = "C:\\test2.xsd";

File file1 = new File(sourceLoc);
File file2 = new File(targetLoc);

final ResourceSet resourceSet = new ResourceSetImpl();
final Resource res1 =
resourceSet.getResource(URI.createURI(file1.toURI().toString ()), true);
final Resource res2 =
resourceSet.getResource(URI.createURI(file2.toURI().toString ()), true);

XSDSchema sourceSchema = ((XSDResourceImpl) res1).getSchema();
XSDSchema targetSchema = ((XSDResourceImpl) res2).getSchema();

XSDElementDeclaration srcComponent =
sourceSchema.getElementDeclarations().get(0);
XSDElementDeclaration oldComponent =
targetSchema.getElementDeclarations().get(0);

Element element = srcComponent.getElement();
if (element != null) {
final Node newComponent =
targetSchema.getDocument().importNode(srcComponent.getElemen t(), true);
targetSchema.getElement().replaceChild(newComponent,
oldComponent.getElement());
targetSchema.getDocument().normalizeDocument();
}

targetSchema.validate();
final Collection<XSDDiagnostic> diag = targetSchema.getAllDiagnostics();
if (diag != null && !diag.isEmpty()) {
for (final XSDDiagnostic dia : diag) {
System.out.println(dia.getMessage());
}
}
Resource resource = targetSchema.eResource();
try {
resource.save(Collections.EMPTY_MAP);
} catch (IOException e) {
e.printStackTrace();
}
}

public void selectionChanged(IAction action, ISelection selection) {
}

}

------------------------------------------------------------ ------
Validation falis with below message
------------------------------------------------------------ ------
XSD: Type reference 'tns1#simple1' is unresolved, which is true as
replacechild() method should have defined "tns1" in element ?

Am i doing something wrong or is there any other way to do this.

Bhuvan,

It's unlikely I'll have time to look at this before June 26th,
especially if I have to set up a project to even run this scenario.

Bhuvan,

Keep in mind that DOM doesn't know that type="..." contains a QName so
don't expect it to handle that the same was as when a QName is used in
an element or attribute. As far as DOM is concerned the values of
attributes are always just strings. So no, don't expect this to work
without effort...
