使用EMF以字符串格式解析XML

Question

我已经使用EMF生成了基于XSD的访问功能。我可以看到如何在生成的示例中从磁盘文件中加载输入。但是，我要解析的XML存储在字符串中。有什么办法可以继续而不将字符串倒入文件中然后读回文件？

这是一个示例方法，在模型串和解析XML并返回eobject的ecorepackage实例中。

public static EObject loadEObjectFromString(String myModelXml, EPackage ePackage) throws IOException { 
    // Create a ResourceSet
    ResourceSet resourceSet = new ResourceSetImpl();
    // register XMIRegistryResourceFactoryIml
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put
    (Resource.Factory.Registry.DEFAULT_EXTENSION, 
     new XMIResourceFactoryImpl());
     // register your epackage to the resource set so it has a reference to your ecore
     // you can get an instance to your epackage by calling YourEPackageClass.getInstace();
    resourceSet.getPackageRegistry().put(ePackage.getNsURI(), ePackage);
    Resource resource = resourceSet.createResource(URI.createURI("*.modelextension"));
    resource.load(new URIConverter.ReadableInputStream(myModelXml), null);
    // return the root model object and there you have it, all you need is to
    // cast it to the right EObject based on your model 
    return resource.getContents().get(0);
}
