The following code shows you how to use the DOMImplementationLS and DOMConfiguration classes to validate an XML document only when an XML Schema is present: DOMImplementationLS DOMiLS=null;//get a LSParserLSParser LSP=DOMiLS.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS, “http://www.w3.org/2001/XMLSchema”); //get a DOMConfigurationDOMConfiguration DOMc=LSP.getDomConfig();//validatingif(DOMc.canSetParameter(“schema-type”,”http://www.w3.org/2001/XMLSchema”))DOMc.setParameter(“schema-type”,”http://www.w3.org/2001/XMLSchema”);else System.out.println(“Error…”);//use validate-if-schemaif(DOMc.canSetParameter(“validate-if-schema”,true)) DOMc.setParameter(“validate-if-schema”,true); else System.out.println(“Error…”);
