Creating DOMImplementationLS Objects

1. Use the feature "LS" or "LS-Async" to find a DOMImplementation object that supports Load and Save.

2. Cast the DOMImplementation object to DOMImplementationLS.

System.setProperty(DOMImplementationRegistry.PROPERTY,
  "org.apache.xerces.dom.DOMImplementationSourceImpl");
DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
DOMImplementation impl = registry.getDOMImplementation("XML 1.0 LS 3.0");
  if (impl != null) {
    DOMImplementationLS implls = (DOMImplementationLS) impl;
    // ...
  }
