Use dom4j to create an XML file

The Code is as follows:

1 package XML; 2 3 Import Java. io. filewriter; 4 Import Java. io. ioexception; 5 import Java. io. writer; 6 Import Org. dom4j. document; 7 Import Org. dom4j. export enthelper; 8 Import Org. dom4j. element; 9 Import Org. dom4j. io. outputformat; 10 Import Org. dom4j. io. xmlwriter; 11 12 public class dom4jcreatexml {13 public void testcreatexml () {14 // create an XML document 15 document DOC = documenthelper. createdocument (); 16 // to XML Add Comment 17 Doc. addcomment ("here is the comment"); 18 // create a node named students. because it is the first creation, it is the root node. If you create a node through doc, an error is returned. 19 element root = Doc. addelement ("Students"); 20 // create a node named student under the root node 21 element stuele = root. addelement ("student"); 22 // Add attribute 23 to student node. addattriele ("ID", "101"); 24 // Add a subnode 25 element nameele = stuele to the student node. addelement ("name"); 26 // set the subnode text 27 nameele. settext ("Zhang San"); 28 // used to format the XML content and set the header label 29 outputformat format = outputformat. createprettyprint (); 30 // set the XML document encoding to utf-831 format. setencoding ("UTF-8"); 32 writer out; 33 try {34 // create an output stream object 35 out = new filewriter ("E: // XML // new. XML "); 36 // create a dom4j object to create XML 37 xmlwriter writer = new xmlwriter (Out, format ); 38 // call the write method to write the DOC file to the specified path 39 writer. write (DOC); 40 writer. close (); 41 system. out. print ("XML file generated successfully"); 42} catch (ioexception e) {43 system. out. print ("failed to generate xml file"); 44 E. printstacktrace (); 45} 46} 47 48 public static void main (string [] ARGs) {49 dom4jcreatexml xml = new dom4jcreatexml (); 50 XML. testcreatexml (); 51} 52}

Generated XML file:

1 <? XML version = "1.0" encoding = "UTF-8"?> 2 3 <! -- Here is the comment --> 4 <students> 5 <student ID = "101"> 6 <Name> Zhang San </Name> 7 </student> 8 </students>
