Java中SAX解析XML并在控制台原样输出

昨天用了DOM解析XML文件并原样输出，今天上网看见了还有SAX解析，两者的区别是DOM解析是按节点解析，SAX解析是按行解析，废话不多说，上代码吧

public class ParseXML {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
SAXParserFactory factory=SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
parser.parse("src/hello.xml", new MyHandle());
}
}

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class MyHandle extends DefaultHandler {

@Override
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
System.out.print("<"+qName);
int length=attributes.getLength();
for (int i = 0; i < length; i++) {
System.out.print(" "+attributes.getQName(i)+"=\""+attributes.getValue(i)+"\"");
}
System.out.print(">");
}

@Override
public void endElement(String uri, String localName, String qName)
throws SAXException {
System.out.print("</"+qName+">");
}

@Override
public void characters(char[] ch, int start, int length)
throws SAXException {
String value=new String(ch, start, length);
System.out.print(value);
}
}

不得不说SAX解析比DOM解析简单多了，昨天用DOM解析，头都被节点弄昏了，今天用SAX解析还是很快就写完了，还是很开心啊，技多不压身，哈哈，睡觉
