场景:使用dom4j生成以下xml文件
<?xml version="1.0" encoding="UTF-8"?> <result> <code>1</code> <data> <person> <name>张三</name> <id>1</id> <url>http://192.168.191.1:9999/TestWeb/c7fe21616d2a5e2bd1e84bd453a5b30f.jpg</url> <courses> <course> <courseName>语文</courseName> <courseMarks>90</courseMarks> <courseId>1</courseId> </course> <course> <courseName>数学</courseName> <courseMarks>80</courseMarks> <courseId>2</courseId> </course> <course> <courseName>英语</courseName> <courseMarks>70</courseMarks> <courseId>3</courseId> </course> </courses> </person> <person name="李四" id="2" url="http://192.168.191.1:9999/TestWeb/4052858c526002a712ef574ccae1948f.jpg"> <course courseName="语文" courseMarks="91" courseId="1"/> <course courseName="数学" courseMarks="82" courseId="1"/> <course courseName="英语" courseMarks="73" courseId="1"/> </person> </data> </result>
以下是实现代码:
import java.io.FileWriter; import java.io.IOException; import org.dom4j.Document; import org.dom4j.DocumentHelper; import org.dom4j.Element; import org.dom4j.io.OutputFormat; import org.dom4j.io.XMLWriter; public class TestXML { public static void main(String[] args) { FileWriter out = null; try { out = new FileWriter( "src/foo.xml" ); //写入文件 createDocument().write( out ); OutputFormat format = OutputFormat.createPrettyPrint(); //转换成字符串 format.setEncoding("UTF-8"); XMLWriter writer = new XMLWriter( System.out, format ); writer.write( createDocument() ); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }finally{ if (out!=null) { try { out.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } public static Document createDocument() { Document document = DocumentHelper.createDocument(); Element root = document.addElement( "result" ); root.addElement("code").addText("1"); Element data = root.addElement("data"); Element person1 = data.addElement( "person" ); person1.addElement( "name" ).setText("张三"); person1.addElement( "id" ).setText("1"); person1.addElement( "url" ).setText("http://192.168.191.1:9999/TestWeb/c7fe21616d2a5e2bd1e84bd453a5b30f.jpg"); Element courses1 =person1.addElement( "courses" ); Element course1 = courses1.addElement( "course" ); course1.addElement( "courseName" ).setText("语文"); course1.addElement( "courseMarks" ).setText("90"); course1.addElement( "courseId" ).setText("1"); Element course2 = courses1.addElement( "course" ); course2.addElement( "courseName" ).setText("数学"); course2.addElement( "courseMarks" ).setText("80"); course2.addElement( "courseId" ).setText("2"); Element course3 = courses1.addElement( "course" ); course3.addElement( "courseName" ).setText("英语"); course3.addElement( "courseMarks" ).setText("70"); course3.addElement( "courseId" ).setText("3"); Element person2 = data.addElement( "person" ) .addAttribute( "name", "李四" ) .addAttribute( "id", "2" ) .addAttribute("url", "http://192.168.191.1:9999/TestWeb/4052858c526002a712ef574ccae1948f.jpg"); person2.addElement( "course" ) .addAttribute( "courseName", "语文" ) .addAttribute( "courseMarks", "91" ) .addAttribute( "courseId", "1" ); person2.addElement( "course" ) .addAttribute( "courseName", "数学" ) .addAttribute( "courseMarks", "82" ) .addAttribute( "courseId", "1" ); person2.addElement( "course" ) .addAttribute( "courseName", "英语" ) .addAttribute( "courseMarks", "73" ) .addAttribute( "courseId", "1" ); return document; } }
