Hi all, Another problem with DOM support:
The method getDocumentElement will generate an exception if the DOMDocument has no root element. It should return null in this case. Looking into the DOMNodeHelper class shows that if ( (element instanceof org.w3c.dom.Element) ) { return (org.w3c.dom.Element) element; } else { // Use DOMWriter? notSupported(); return null; } Will generate this exception if element is null. So i patched the source to return null if element is null. I do this for all other asDOMxxx methods too.

System.out.println( "Cannot convert: " + node + " into a W3C DOM Node"); notSupported(); return null; } } public static org.w3c.dom.Document asDOMDocument(Document document) { if ( (document == null) || (document instanceof org.w3c.dom.Document) ) { return (org.w3c.dom.Document) document; } else { // Use DOMWriter? notSupported(); return null; } } public static org.w3c.dom.DocumentType asDOMDocumentType(DocumentType documentType) { if ((documentType == null) || (documentType instanceof org.w3c.dom.DocumentType) ) { return (org.w3c.dom.DocumentType) documentType; } else { // Use DOMWriter? notSupported(); return null; } } public static org.w3c.dom.Text asDOMText(CharacterData text) { if ((text == null) || (text instanceof org.w3c.dom.Text) ) { return (org.w3c.dom.Text) text; } else { // Use DOMWriter? notSupported(); return null; } } public static org.w3c.dom.Element asDOMElement(Node element) { if ( (element == null) || (element instanceof org.w3c.dom.Element) ) { return (org.w3c.dom.Element) element; } else { // Use DOMWriter? notSupported(); return null; } } public static org.w3c.dom.Attr asDOMAttr(Node attribute) { if ( (attribute == null) || (attribute instanceof org.w3c.dom.Attr) ) { return (org.w3c.dom.Attr) attribute; } else { // Use DOMWriter? notSupported(); return null; } } ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
