package demo;
import java.io.File;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class JieXiXML {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
DocumentBuilderFactory bdf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = bdf.newDocumentBuilder();
Document document = db.parse( new File( "user.xml" ));
NodeList list = document.getElementsByTagName( "usa" );
System.out.println( "服务器之家测试结果:" );
for ( int i = 0 ; i < list.getLength(); i++) {
Element element = (Element)list.item(i);
String name = element.getElementsByTagName( "name" ).item( 0 ).getFirstChild().getNodeValue();
System.out.println(name);
String pass = element.getElementsByTagName( "pass" ).item( 0 ).getFirstChild().getNodeValue();
System.out.println(pass);
System.out.println( "------------------" );
}
}
