大家好，欢迎来到IT知识分享网。

// XML转List
List<Map<String,String>> list =new ArrayList<Map<String,String>>();

SAXReader reader = new SAXReader();
            
Reader stringReader = new StringReader(strReturn);
            
Document document = reader.read(stringReader);
            
Element rootElement = document.getRootElement();
            
listNodes(rootElement,list,"0");

public static List<Map<String, String>> listNodes(Element node, List<Map<String,String>> list, String flag) {
        if(node.getName().equals("L_VALUESET_TAB_ITEM")){
            Map<String,String> para=new HashMap<String, String>();
            Element FLEX_VALUE = node.element("FLEX_VALUE");
            Element FLEX_DESC = node.element("FLEX_DESC");
            Element ENABLED_FLAG = node.element("ENABLED_FLAG");
            if (StringUtils.equalsIgnoreCase("Y", ENABLED_FLAG.getText())) {
                para.put("EBS_SHOP_ID", FLEX_VALUE.getText());
                para.put("EBS_SHOP_NM", FLEX_DESC.getText());
                para.put("ENABLED_FLAG", ENABLED_FLAG.getText());
                para.put("FLAG", flag);
                list.add(para);
            }
        }
        // 当前节点下面子节点迭代器
        Iterator<Element> it = node.elementIterator();
        // 遍历
        while (it.hasNext()) {
            // 获取某个子节点对象
            Element e = it.next();
            // 对子节点进行遍历
            listNodes(e,list,flag);
        }
        return list;
    }

另外一个例子

book.xml数据如下：

<books>
    <book>
        <author>Thomas</author>
        <title>Java从入门到放弃</title>
        <publisher>UCCU</publisher>
    </book>
    <book>
        <author>小白</author>
        <title>MySQL从删库到跑路</title>
        <publisher>Go Die</publisher>
    </book>
    <book>
        <author>PHPer</author>
        <title>Best PHP</title>
        <publisher>PHPchurch</publisher>
    </book>
</books>

        System.out.println("出版社："+publisher.getText());
    }
