第一种 DOM 实现方法
Java代码
import java io File;
import javax xml parsers DocumentBuilder;
import javax xml parsers DocumentBuilderFactory;
import w c dom Document;
import w c dom NodeList;
public class MyXMLReader DOM {
public static void main(String arge[]) {
long lasting = System currentTimeMillis();
try {
File f = new File( data_ k xml );
DocumentBuilderFactory factory = DocumentBuilderFactory newInstance();
DocumentBuilder builder = factory newDocumentBuilder();
Document doc = builder parse(f);
NodeList nl = doc getElementsByTagName( VALUE );
for (int i = ; i < nl getLength(); i++) {
System out print( 车牌号码: + doc getElementsByTagName( NO em(i) getFirstChild() getNodeValue());
System out println( 车主地址: + doc getElementsByTagName( ADDR em(i) getFirstChild() getNodeValue());
System out println( 运行时间 + (System currentTimeMillis() lasting)
+ 毫秒 );
}
}
} catch (Exception e) {
e printStackTrace();
}
}
}
第二种 DOM J实现方法
Java代码
import java io *;
import java util *;
import dom j *;
import dom j io *;
public class MyXMLReader DOM J {
public static void main(String arge[]) {
long lasting = System currentTimeMillis();
try {
File f = new File( data_ k xml );
SAXReader reader = new SAXReader();
Document doc = reader read(f);
Element root = doc getRootElement();
Element foo;
for (Iterator i = root elementIterator( VALUE ); i hasNext();) {
foo = (Element) i next();
System out print( 车牌号码: + foo elementText( NO ));
System out println( 车主地址: + foo elementText( ADDR ));
}
System out println( 运行时间 + (System currentTimeMillis() lasting)
+ 毫秒 );
}
} catch (Exception e) {
e printStackTrace();
}
}
}
第三种 JDOM实现方法
Java代码
import java io *;
import java util *;
import jdom *;
import jdom input *;
public class MyXMLReader JDOM {
public static void main(String arge[]) {
long lasting = System currentTimeMillis();
try {
SAXBuilder builder = new SAXBuilder();
Document doc = builder build(new File( data_ k xml ));
Element foo = doc getRootElement();
List allChildren = foo getChildren();
for (int i = ; i < allChildren size(); i++) {
System out print( 车牌号码: + ((Element) allChildren get(i)) getChild( NO ) getText());
System out println( 车主地址: + ((Element) allChildren get(i)) getChild( ADDR ) getText());
}
System out println( 运行时间 + (System currentTimeMillis() lasting)
+ 毫秒 );
}
} catch (Exception e) {
e printStackTrace();
}
}
}
第四种SAX实现方法
Java代码
import javax xml parsers SAXParser;
import javax xml parsers SAXParserFactory;
import xml sax Attributes;
import xml sax InputSource;
import xml sax SAXException;
import xml sax helpers DefaultHandler;
public class MyXMLReader SAX extends DefaultHandler {
java util Stack tags = new java util Stack();
public MyXMLReader SAX() {
super();
}
public static void main(String args[]) {
long lasting = System currentTimeMillis();
try {
SAXParserFactory sf = SAXParserFactory newInstance();
SAXParser sp = sf newSAXParser();
MyXMLReader SAX reader = new MyXMLReader SAX();
sp parse(new InputSource( data_ k xml ) reader);
} catch (Exception e) {
e printStackTrace();
}
System out println( 运行时间 + (System currentTimeMillis() lasting)
+ 毫秒 );
}
public void characters(char ch[] int start int length)
throws SAXException {
String tag = (String) tags peek();
if (tag equals( NO )) {
System out print( 车牌号码 + new String(ch start length));
}
if (tag equals( ADDR )) {
System out println( 地址: + new String(ch start length));
}
}
public void startElement(String uri String localName String qName
Attributes attrs) {
tags push(qName);
