下面附上Cute3.java(利用jdom解析xml,即遍歷),希望能夠對下面的Cute3.java修改從而能夠實現我所說的編碼,應該如何來修改下面的java代碼呢？
import org.jdom.*;
import org.jdom.input.SAXBuilder;
import java.io.IOException;
import java.util.*;
public class Cute3 {
public static void main(String args[]){
String url = "D:\\netbeanssy\\Jdom\\src\\jdom\\mine.xml";
try {
SAXBuilder parser = new SAXBuilder();
Document document = parser.build(url);
process(document.getRootElement());
} catch (JDOMException e) {
System.out.println(url + " is not well-formed.");
} catch (IOException e) {
System.out.println("Due to an IOException,the parser could not encode "+ url);
}
}
public static void process(Element element) {
List content = element.getContent();
Iterator iterator = content.iterator();
String qualifiedName = element.getQualifiedName();
System.out.println(qualifiedName + ":" + element.getTextNormalize());
List attributes = element.getAttributes();
if (!attributes.isEmpty()) {
Iterator iterator1 = attributes.iterator();
while (iterator1.hasNext()) {
Attribute attribute = (Attribute) iterator1.next();
String name = attribute.getName();
String value = attribute.getValue();
System.out.println(name + ':' + value);
}
}
while (iterator.hasNext()) {
Object o = iterator.next();
if (o instanceof Element) {
Element child = (Element)o;
process(child);
}
}
}
}

可以實現上述效果的修改後的詳細代碼信息如下：
Java code:
import org.jdom.*;
import org.jdom.input.SAXBuilder;
import java.io.IOException;
import java.util.*;
public class Cute3 {
public static void main(String args[]){
String url = "G:\\mine.xml";
try {
SAXBuilder parser = new SAXBuilder();
Document document = parser.build(url);
process(document.getRootElement(), "", 1);
} catch (JDOMException e) {
System.out.println(url + " is not well-formed.");
} catch (IOException e) {
System.out.println("Due to an IOException,the parser could not encode "+ url);
}
}
public static void process(Element element, String s, int n) {
List content = element.getContent();
Iterator iterator = content.iterator();
String qualifiedName = element.getQualifiedName();
System.out.println(qualifiedName + " : " + s + (new Integer(n)).toString());
int m = 1;
List attributes = element.getAttributes();
if (!attributes.isEmpty()) {
Iterator iterator1 = attributes.iterator();
while (iterator1.hasNext()) {
Attribute attribute = (Attribute) iterator1.next();
String name = attribute.getName();
String value = attribute.getValue();
System.out.println(name + " : " + s + (new Integer(n)).toString() + "." + (new Integer(m)).toString());
if(!value.equals("")){
System.out.println(value + " : " + s + (new Integer(n)).toString() + "." + (new Integer(m)).toString() + ".1");
}
m++;
}
}
if(!element.getTextNormalize().equals("")){
System.out.println(element.getTextNormalize() + " : " + s + (new Integer(n)).toString() + "." + m);
}
while (iterator.hasNext()) {
Object o = iterator.next();
if (o instanceof Element) {
Element child = (Element)o;
process(child, s + (new Integer(n)).toString() + ".", m);
m++;
}
}
n++;
}
}
