Java-读取XML文件

可能的实现之一：

File file = new File("userdata.xml");documentBuilderFactory documentBuilderFactory = documentBuilderFactory        .newInstance();documentBuilder documentBuilder = documentBuilderFactory.newdocumentBuilder();document document = documentBuilder.parse(file);String usr = document.getElementsByTagName("user").item(0).getTextContent();String pwd = document.getElementsByTagName("password").item(0).getTextContent();

与XML内容一起使用时：

<credentials>    <user>testusr</user>    <password>testpwd</password></credentials>

结果

"testusr"

"testpwd"

usr

pwd
