XML读取的例子

今天需要用到用SAX对XML进行读取，在GOOGLE上看了很多例子，发现了一个写的比较好的。

他的例子xml如下

<?xml version="1.0"?>
<company>
    <staff>
        <firstname>yong</firstname>
        <lastname>mook kim</lastname>
        <nickname>§</nickname>
        <salary>100000</salary>
    </staff>
</company>

读取的代码如下：

package com.mkyong.test;
 
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
 
public class ReadXMLUTF8FileSAX 
{
    public static void main( String[] args )
    {
        try {
 
              SAXParserFactory factory = SAXParserFactory.newInstance();
              SAXParser saxParser = factory.newSAXParser();
 
              DefaultHandler handler = new DefaultHandler() {
 
                boolean bfname = false;
                boolean blname = false;
                boolean bnname = false;
                boolean bsalary = false;
 
                public void startElement(String uri, String localName,
                    String qName, Attributes attributes)
                    throws SAXException {
 
                  System.out.println("Start Element :" + qName);
 
                  if (qName.equalsIgnoreCase("FIRSTNAME")) {
                      bfname = true;
                  }
 
                  if (qName.equalsIgnoreCase("LASTNAME")) {
                      blname = true;
                  }
 
                  if (qName.equalsIgnoreCase("NICKNAME")) {
                      bnname = true;
                  }
 
                  if (qName.equalsIgnoreCase("SALARY")) {
                      bsalary = true;
                  }
 
                }
 
                public void endElement(String uri, String localName,
                        String qName)
                        throws SAXException {
 
                      System.out.println("End Element :" + qName);
 
                }
 
                public void characters(char ch[], int start, int length)
                    throws SAXException {
 
                  System.out.println(new String(ch, start, length));
 
 
                  if (bfname) {
                    System.out.println("First Name : "
                        + new String(ch, start, length));
                    bfname = false;
                  }
 
                  if (blname) {
                      System.out.println("Last Name : "
                          + new String(ch, start, length));
                      blname = false;
                   }
 
                  if (bnname) {
                      System.out.println("Nick Name : "
                          + new String(ch, start, length));
                      bnname = false;
                   }
 
                  if (bsalary) {
                      System.out.println("Salary : "
                          + new String(ch, start, length));
                      bsalary = false;
                   }
 
                }
 
              };
 
              File file = new File("c:\\file.xml");
              InputStream inputStream= new FileInputStream(file);
              Reader reader = new InputStreamReader(inputStream,"UTF-8");
 
              InputSource is = new InputSource(reader);
              is.setEncoding("UTF-8");
 
              saxParser.parse(is, handler);
 
 
            } catch (Exception e) {
              e.printStackTrace();
            }
 
    }
}
