本文介绍如何使用Dom4j库解析XML字符串，并提取关键属性值。通过具体示例展示了Dom4j的基本用法，包括创建SAXReader对象、读取XML内容、获取根元素及属性值。

引入Dom4j依赖

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

Dom4j解析

    public static void main(String[] args) {

        String xml = "<Response retCode=\"000\" scoreID=\"1920011\" score=\"848\" fraud=\"5\" />";
        InputStream is = null;
        try {
            SAXReader reader = new SAXReader();
            is = new ByteArrayInputStream(xml.getBytes("UTF-8"));
            Document doc = reader.read(is);
            Element root = doc.getRootElement();
            
            String retCode = root.attributeValue("retCode");
            String scoreID = root.attributeValue("scoreID");
            String score = root.attributeValue("score");
            String fraud = root.attributeValue("fraud");
            
            System.out.println("retCode: " + retCode + " scoreID: " + scoreID + " score: " + score + " fraud: " + fraud);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != is) {
                    is.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

处理结果

retCode: 000 scoreID: 1920011 score: 848 fraud: 5
