The method resolveReference resolves the reference of the node and returns a SAXSource with the parserand the parser's input source. It takes as arguments an AuthorNode that represents the node for which the referenceneeds resolving, the systemID of the node, the AuthorAccess with access methods to the Author data model anda SAX EntityResolver which resolves resources that are already opened in another editor or resolve resourcesthrough the XML catalog. In the implementation you need to resolve the reference relative to the systemID, andcreate a parser and an input source over the resolved reference.public SAXSource resolveReference(AuthorNode node,String systemID,AuthorAccess authorAccess,EntityResolver entityResolver) {SAXSource saxSource = null;if (node.getType() == AuthorNode.NODE_TYPE_ELEMENT) {AuthorElement element = (AuthorElement) node;if ("ref".equals(element.getLocalName())) {AttrValue attrValue = element.getAttribute("location");if (attrValue != null) {String attrStringVal = attrValue.getValue();try {URL absoluteUrl = new URL(new URL(systemID),authorAccess.correctURL(attrStringVal));InputSource inputSource = entityResolver.resolveEntity(null,absoluteUrl.toString());if(inputSource == null) {inputSource = new InputSource(absoluteUrl.toString());}XMLReader xmlReader = authorAccess.newNonValidatingXMLReader();xmlReader.setEntityResolver(entityResolver);}}}saxSource = new SAXSource(xmlReader, inputSource);} catch (MalformedURLException e) {logger.error(e, e);} catch (SAXException e) {logger.error(e, e);} catch (IOException e) {logger.error(e, e);}}return saxSource;
