控制台错误：

java代码：

package org.email;
 
import java.io.FileReader;
import java.io.IOException;
import javax.xml.parsers.ParserConfigurationException;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class SaxReadXml extends DefaultHandler {
    public static void main(String[] args) throws ParserConfigurationException,
           SAXException, IOException {
 
       XMLReader xr = XMLReaderFactory
              .createXMLReader("org.apache.xerces.parsers.SAXParser");
       xr.setContentHandler(new SaxReadXml());
       xr.parse(new InputSource(new FileReader(
              "D://WORK//SendEmail//src//Config.xml")));
    }
 
    public void characters(char[] ch, int start, int length)
           throws SAXException {
 
       String data = new String(ch, start, length);
       System.out.println("E-mail：" + data);
 
    }
}

XML文档：

<?xml version="1.0" encoding="UTF-8"?>

    </email>

    <!-- me -->

    <email>

       <receiver>1058106015@qq.com</receiver>

原因分析：注意此处注释：<!--王小林-->与下方得区别<!-- me -->

王小林后面少了一个空格。
