xml转map

map转xml

public static String ArrayToXml(HashMap<String, String> arr) {        String xml = "<xml>";        Iterator<Entry<String, String>> iter = arr.entrySet().iterator();        while (iter.hasNext()) {            Entry<String, String> entry = iter.next();            String key = entry.getKey();            String val = entry.getValue();            if (IsNumeric(val)) {                xml += "<" + key + ">" + val + "</" + key + ">";            } else                xml += "<" + key + "><![CDATA[" + val + "]]></" + key + ">";        }        xml += "</xml>";        return xml;    }    public static boolean IsNumeric(String str) {        if (str.matches("\\d *")) {            return true;        } else {            return false;        }    }
