dom4j解析xml文档

SAXReader  saxReader = new SAXReader();

//要读取的xml文档路径

String filePath = Dom4jTest.class.getResource("xml/test.xml").toURI().getPath();

File file = new File(filePath);
Document document = saxReader.read(file);
Element rootNode = document.getRootElement();
if(null != rootNode) {
Element keyE ;
keyE = rootNode.element("listener");
Element keyL = keyE.element("listener-class");
System.out.println(keyL.getTextTrim());
}

//写入xml文档的话用OutputFormat先设置编码，避免产生乱码

private static OutputFormat format = OutputFormat.createPrettyPrint();

format.setEncoding("UTF-8");
