Need to include possibility for String version to be null. Currently failing DOM L3 Core test case nodegetfeature01. See CoreDOMImplementationImpl.hasFeature for reference. Proposed patch in CoreDocumentImpl.getFeature: public Object getFeature(String feature, String version) { + boolean anyVersion = version == null || version.length() == 0; if ((feature.equalsIgnoreCase("XPath") - || feature.equalsIgnoreCase("+XPath"))&& version.equals("3.0")){ + || feature.equalsIgnoreCase("+XPath"))&& (anyVersion||version.equals + ("3.0"))){ try{ Class xpathClass = ObjectFactory.findProviderClass( "org.apache.xpath.domapi.XPathEvaluatorImpl", ObjectFactory.findClassLoader(), true); fXPathEvaluator = xpathClass.newInstance(); java.lang.reflect.Method setDocument = xpathClass.getMethod ("setDoc", new Class[]{Document.class}); setDocument.invoke(fXPathEvaluator, new Object[]{this}); return fXPathEvaluator; } catch (Exception e){ //e.printStackTrace(); return null; } } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
