通过Java方法传递参数更新XML标签值的教程

            File xmlFile = new File("input.xml"); // 替换为你的XML文件路径
            StreamSource xmlSource = new StreamSource(xmlFile);

            // 2. 加载XSLT转换文件

            Transformer transformer = factory.newTransformer(xsltSource);

            // 4. 设置参数
            transformer.setParameter("newValue", newValue1); // 传递value1的值，更新<name>标签
            // 传递value2的值，更新<location>标签，需要创建新的XSLT转换文件或者修改现有的XSLT文件来匹配<location>标签
            // 如果需要同时更新多个标签，可以创建多个XSLT文件，或者在同一个XSLT文件中定义多个template

            // 5. 执行转换

            StreamResult result = new StreamResult(writer);
            transformer.transform(xmlSource, result);

            String output = writer.toString();
            System.out.println(output);
