dom4j maven依赖

<dependency>
          <groupId>dom4j</groupId>
          <artifactId>dom4j</artifactId>
          <version>1.6.1</version>
        </dependency>

xml转换为map的方法源码

/**
         *
         * @param xml 要转换的xml字符串
         * @param charset 字符编码
         * @return  转换成map后返回结果
         * @throws UnsupportedEncodingException
         * @throws DocumentException
         */
        public static Map<String, String> xmlToMap(String xml, String charset) throws UnsupportedEncodingException, DocumentException{
    
            Map<String, String> respMap = new HashMap<String, String>();
    
            SAXReader reader = new SAXReader();
            Document doc = reader.read(new ByteArrayInputStream(xml.getBytes(charset)));
            Element root = doc.getRootElement();
            xmlToMap(root, respMap);
            return respMap;
        }
    
        public static Map<String, String> xmlToMap(Element tmpElement, Map<String, String> respMap){
            ArrayList<String> strings = new ArrayList<String>();
            for (String s:strings
                 ) {
                
            }
            if (tmpElement.isTextOnly()) {
                respMap.put(tmpElement.getName(), tmpElement.getText());
                return respMap;
            }
    
            @SuppressWarnings("unchecked")
            Iterator<Element> eItor = tmpElement.elementIterator();
            while (eItor.hasNext()) {
                Element element = eItor.next();
                xmlToMap(element, respMap);
            }
            return respMap;
        }

注意导包不要搞错

import org.dom4j.Document;
    import org.dom4j.DocumentException;
    import org.dom4j.Element;
    import org.dom4j.io.SAXReader;

测试数据

<note>
    <to>George</to>
    <from>John</from>
    <heading>Reminder</heading>
    <body>Don't forget the meeting!</body>
    </note>

测试之后得出的map调用toString并打印输出，得到的结果

{to=George, body=Don't forget the meeting!, from=John, heading=Reminder}
