 SAX一下问题
import javax.xml.parsers.*; import org.xml.sax.helpers.*; import org.xml.sax.*; import java.io.*; public class sax_3 { public static void main(String args[])
{
try {
SAXParserFactory factory=SAXParserFactory.newInstance() ;
factory.setNamespaceAware (true);
SAXParser saxParser=factory.newSAXParser();
MyHandler handler=new MyHandler();
saxParser.parse(new File("1.xml"),handler);
}
catch(Exception e)
{ System.out.println(e);}
}
}
class MyHandler extends DefaultHandler
{
boolean isComputabled=false,math=false,english=false;
int count_1=0,count_2=0,count_3=0;
float mathSum=0,englishSum=0,sum=0;
public void characters(char[] ch,int start,int length)
{
String text=new String(ch,start,length);
if(isComputabled==true)
{
String str=text.trim();
if(str.length()>0)
{
int d=Integer.parseInt(str);
sum=sum+d;
if(math)
mathSum=mathSum+d;
if(english)
englishSum=englishSum+d;
isComputabled=false;
}
}
System.out.print(text);
}
public void startElement(String uri,String localName,
String qName,Attributes atts)
{
String str=null;
if(uri.length()>0)
str=uri;
System.out.print("<"+qName);
if(qName.endsWith("月薪"))
{
count_1 ++;
isComputabled=true;
}
for(int k=0;k<atts.getLength();k++)
{
System.out.print(" "+atts.getLocalName(k)+"= ");
System.out.print("\""+atts.getValue(k)+"\"");
if(atts.getValue(k).startsWith("科长"))
{
math=true;
count_2 ++;
}
if(atts.getValue(k).startsWith("科员"))
{
english=true;
count_3 ++;
}
}
System.out.print(">");
}
public void endElement(String uri,String localName,String qName)
{
System.out.print("</"+qName+">");
}
public void endDocument()
{
System.out.println(" ");
System.out.println("人员总数:"+count_1);
System.out.println("科长人数:"+count_2);
System.out.println("科长人数:"+count_3);
System.out.println("工资总额:"+sum);
System.out.println("科长工资总额:"+mathSum);
System.out.println("科员工资总额:"+englishSum);
}
}
为什么这样解析 工资总额和科长工资总额都相同啊 怎么处理啊
