The so-called JDOM, the simplest understanding method is Java XML = JDOM. An example of a simple operation XML is provided below.
1. The following is an XML file used by the example:
/ **
* Located in the root directory of the C drive
* ABC.XML
** /
jhgjg </ title> <content> jhgjg </ content> <email> jhjh </ email> </ message> <message id = "fdsa"> <title> fdsa </ title> <content> Fasdf </ content> <email> fsadfa </ email> </ message> </ messages></p>
<p>2, procedure for operating XML</p>
<p>/ **</p>
<p>* Myjdom.java</p>
<p>** /</p>
<p>Package com.test; import org.jdom. *; import org.jdom.input. *; import org.jdom.output. *;</p>
<p>Import java.io.fileinputStream; import java.io.fileoutputstream; import java.util.list;</p>
<p>Public class myjdom {</p>
<p>Public static void main (string [] args) throws exception {saxbuilder sb = new saxbuilder (); // Establish constructor Document Doc = Sb.Build (New FileInputStream ("c: //abc.xml")); ///// Read in the specified file</p>
<p>Element root = doc.getrootelement (); // Get root node list = root.getchildren (); // put all child nodes under the root node into list</p>
<p>For (int I = 0; i <list.size (); i ) {</p>
<p>System.out.println ("------------------------");</p>
<p>ELEMENT ITEM = (Element) list.get (i); // Get a node instance</p>
<p>String name = item.getattribute ("name"). GetValue (); // acquire attribute value</p>
<p>System.out.println ("Name ->" Name;</p>
<p>ELEMENT SUB = Item.getchild ("Title"); // Take the word point String text = sub.gettext (); // get the value of the current node</p>
<p>System.out.println ("Title ->" Text);</p>
<p>Element Sub2 = item.getchild ("content"); string text2 = sub2.gettext ();</p>
<p>System.out.println ("Content ->" TEXT2);</p>
<p>ELEMENT SUB3 = Item.Getchild ("email"); string text3 = Sub3.getText (); system.out.println ("email ->" text3);}}}</p></div><div class="text-center mt-3 text-grey">
