Hi, I just used this option recently:
HashMap parserFeatures = new HashMap();
parserFeatures.put(" http://apache.org/xml/features/nonvalidating/load-external-d td",
Boolean.FALSE);
parserFeatures.put("http://xml.org/sax/features/validation",
Boolean.FALSE);
result.getDefaultLoadOptions().put(XMLResource.OPTION_PARSER _FEATURES,
parserFeatures);
