Java dom4j reads XML instance code _java

Here's an XML read Test I wrote myself

Copy Code code as follows:

Import Java.util.Iterator;


Import Java.io.BufferedReader;


Import Java.io.File;


Import java.io.IOException;


Import Java.io.InputStreamReader;


Import java.net.MalformedURLException;


Import org.dom4j.*;


Import Org.dom4j.io.SAXReader;

public class Xmlread {

static StringBuilder Sbuilder = new StringBuilder ();

public static void Main (string[] args) throws IOException {

BufferedReader breader = new BufferedReader (New InputStreamReader (
system.in));
String path = null;
System.out.println ("Please enter an absolute path to the XML file and file name: \ n");
Path = Breader.readline ();

Sbuilder.append ("Start output XML file content \ n");

        Document document = NULL;
        try {
             document = read (path);
            sbuilder.append (path + "\ n");
       } catch (Malformedurlexception e) {
             E.printstacktrace ();
       } catch (Documentexception e) {
             E.printstacktrace ();
       }

        Element root = getrootelement (document);
        if (root = null) {
             System.out.print ("No access to root node");
            return;
       }
       //Get encoding format for XML documents
        String encstring = document.getxmlencoding ();
        sbuilder.append ("<?xml version=\" 1.0\ "encoding=\" "+ encstring")
                + "\ >\n");
        Sbuilder.append (Elementtext (Root, Atttext (root), 0);

System.out.println (Getiterator (root, 0) + "</" + root.getname () + ">");

}

/**
* Recursive node
*
* @description
* @param element

* @return
*/
private static String Getiterator (element element, int lvl) {

LVL + 1;

for (Iterator i = Element.elementiterator (); I.hasnext ();) {
Element e = (Element) I.next ();
Sbuilder.append (Elementtext (E, Atttext (e), LVL));
Getiterator (e, LVL);

int count = E.nodecount ();

if (Count > 0) {
for (int j = 0; j < lvl; J + +) {
Sbuilder.append ("");
}
}
Sbuilder.append ("</" + e.getname () + ">\n");
}

return sbuilder.tostring ();
}

/**

*
* @description
* @param element
* Current Node
* @return
*/
private static String Atttext (element Element) {

String str = "";
for (int i = 0; i < Element.attributecount (); i++) {
attribute = Element.attribute (i);

STR + + attribute.getname () + "=\" "+ attribute.getvalue () +" "";
}
return str;
}

/**


* Gets the text value of the current element


*


* @description


* @param element


* Current element node


* @param text


* Attribute value


* @param lvl


* Level


* @return


*/


private static String Elementtext (element element, String text, int lvl) {


String str = "";


for (int i = 0; i &lt; lvl; i++) {


STR + + "";


}


STR + + "&lt;" + Element.getname ();


if (text!= null &amp;&amp; text!= "") {


str + text;


}


Since there is no haschild this property or method in the dom4j, the Nodecount () method is used to determine the time and the child nodes.


int count = Element.nodecount ();


if (count = = 0) {


Return str + + "&gt;";


}


Return str + + "&gt;\n";


}
