Get the parser
Dombuilder is primarily used to build existing documents in memory
Saxbuilder is primarily used to build documents based on files or input streams

Saxbuilder builder = new Saxbuilder ();
InputStream in = TestJDOMParser.class.getClassLoader (). getResourceAsStream ("Com/cdsxt/resources/users.xml");
Document to be built
Document doc = Builder.build (in);

Get the root node first and then get the child elements.

Element root = Doc.getrootelement ();
Get all the son elements
List<element> childs = Root.getchildren ();

for (Element child:childs) {
System.out.println (Child.getattributevalue ("id"));
System.out.println (Child.getchildtext ("username"));

All built Documents
Document doc = new document ();

element root = new Element ("Users");

Element user = new Element ("user");
User.setattribute ("id", "Zhanoliu"). SetAttribute ("name", "Test-user");

Element username = new Element ("username");
Username.addcontent ("Fengjie");

element email = new Element ("email");
Email.settext ("[email protected]");

Building relationships
User.setcontent (username);
User.setcontent (email);

Root.addcontent (user);

Doc.setrootelement (root);


Write out the built document

Create a file output
Xmloutputter outputter = new Xmloutputter ();

The default is no format, so to get a formatter to format the session code

Format format = Format.getprettyformat ();
Format.setindent ("");
Outputter.setformat (format);

Building the file output stream
OutputStream out = new FileOutputStream (New File ("F:/tttt.xml"));
Output file
Outputter.output (Doc, out);

Out.flush ();
Out.close ();
