Java implementation of XML format implementation code _java

Core code:

Package com.ddatsh;
Import java.io.IOException;
Import Java.io.StringReader;
Import Java.io.StringWriter;
 
Import java.io.UnsupportedEncodingException;
Import org.dom4j.Document;
Import org.dom4j.DocumentException;
Import Org.dom4j.io.OutputFormat;
Import Org.dom4j.io.SAXReader;
 
Import Org.dom4j.io.XMLWriter; public class Xmlformat {public static string format (String str) throws Exception {Saxreader reader = new Saxread
    ER ();
    SYSTEM.OUT.PRINTLN (reader);
    Note: Create a string of character input stream StringReader in = new StringReader (str);
    Document doc = Reader.read (in);
    System.out.println (Doc.getrootelement ());
    Note: Create output format OutputFormat Formater = Outputformat.createprettyprint ();
    Formater=outputformat.createcompactformat ();
    Note: Sets the output encoding formater.setencoding ("Utf-8") of XML;
    Note: Create output (target) StringWriter out = new StringWriter ();
    Note: Create output stream XMLWriter writer = new XMLWriter (out, formater); Note: Output formatted string to target, after execution.
    The formatted string is saved in out. Writer. write (DOC);
    Writer.close ();
    System.out.println (Out.tostring ());
  Note: Returns the result of our formatted return out.tostring (); public static void Main (string[] args) throws Exception {String head= ' <?xml version=\ ' 1.0\ ' encoding=\ ' gbk\ '
    ?> "; String str = "<requestdata> 

The

Oschina tool for online formatting XML is to use this piece of code.
