e516. preventing expansion of entity references while parsing an xml file.txt

这里面包含了一百多个JAVA源文件

By default, entity references are expanded during parsing. This example demonstrates how to leave the entity references in the DOM document 
Note: The default parser in J2SE 1.4 expands entity references in attribute values. There is no way to prevent this. 

    // Parses an XML file without expanding entity references and returns
    // a DOM document. If validating is true, the contents is validated
    // against the DTD specified in the file.
    public static Document parseXmlFileNoExpandER(String filename, boolean validating) {
        try {
            // Create a builder factory
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            factory.setValidating(validating);
    
            // Prevent expansion of entity references
            factory.setExpandEntityReferences(false);
    
            // Create the builder and parse the file
            Document doc = factory.newDocumentBuilder().parse(new File(filename));
            return doc;
        } catch (SAXException e) {
            // A parsing error occurred; the xml input is not valid
        } catch (ParserConfigurationException e) {
        } catch (IOException e) {
        }
        return null;
    }
