1.解析xml
private Map<String, String> parseXml2Map(String xml, Map<String, String> map) {
    try {
        SAXReader reader = new SAXReader();

            path = map.get(root.getName().trim());
            map.remove(root.getName().trim());
        }
        for (Iterator i = root.elementIterator(); i.hasNext();) {
            Element element = (Element) i.next();
            if (element.isTextOnly()) {
                if (path.length() > 0) {
                    map.put(path + element.getName().trim(), element.getTextTrim());
                } else {

                parseXml2Map(element.asXML(), map);
            }
