关于 xml：WAR 存档中的 Java 编辑文件

//You can loop through your war file using the following code
ZipFile warFile = new ZipFile( warFile );
for( Enumeration e = warFile.entries(); e.hasMoreElements(); )
{
    ZipEntry entry = (ZipEntry) e.nextElement();
    if( entry.getName().contains( yourXMLFile ) )
    {
        //read your xml file
        File fXmlFile = new File( entry );
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(fXmlFile);

        /**Now write your xml file to another file and save it say, createXMLFile **/

        //Appending the newly created xml file and
        //deleting the old one.
        Map<String, String> zip_properties = new HashMap<>();
        zip_properties.put("create","false");
