jsoup 解析html 页面数据

我html 页面元素：

/html/body/table[2]/tbody/tr[1]/td/table/tbody/tr[1]/td[2]/font
/html/body/table[2]/tbody/tr[1]/td/table/tbody/tr[2]/td[2]/div/font/span
/html/body/table[2]/tbody/tr[3]/td/font/b
/html/body/table[2]/tbody/tr[5]/td/div/table/tbody/tr[1]/td[1]/div/b/font/span

以下是代码实现：

　　

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
 
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
 
public class JsoupParseHtml {
 
	public static String getHtmlByUrl(String url){
	    String html = null;
	    //创建httpClient对象
	    HttpClient httpClient = new DefaultHttpClient();
	    //以get方式请求该URL
	    HttpGet httpget = new HttpGet(url);
	    try {
	        //得到responce对象
	        HttpResponse responce = httpClient.execute(httpget);
	        //返回码
	        int resStatu = responce.getStatusLine().getStatusCode();
	        //200正常  其他就不对
	        if (resStatu==HttpStatus.SC_OK) {
	            //获得相应实体
	            HttpEntity entity = responce.getEntity();
	            if (entity!=null) {
	                //获得html源代码
	                html = EntityUtils.toString(entity);  
 
	            }
	        }
	    } catch (Exception e) {
	        System.out.println("访问【"+url+"】出现异常!");
	        e.printStackTrace();
	    } finally {
	        httpClient.getConnectionManager().shutdown();
	    }
	    return html;
	}
 
static String txtpathstr="d:\\one\\";
 
	public static void main(String[] args) throws Exception {
 
		String contents="";
		String urlbase="http://localhost:8080/1.htm";
 
		//String urlbase="http://www.qiushibaike.com/8hr/page/8?s=4513032";//1?s=4513032
	    contents+=gettxtlist(urlbase);
 
		//写入文件
		writefile(contents);
 
	}
 
	public static String gettxtlist(String txturl) throws Exception{
 
		String content="";
		Document doc=jsoupconnect(txturl,360000);
		//Elements els= doc.select("div.content");
 
		Elements els= doc.select("html");
 
		for(Element el:els){
			if (el.select("body").size()>1){
				continue;
			}
			content+=el.text()+"\r\n";
			System.out.println();
			System.out.println(content);
		}
		return content;
	}
 
	public static Document jsoupconnect (String url,int timeout){
		Document doc=null;
		int retry=5;
		while (null==doc&&retry>0){
			retry--;
			try{
			doc= Jsoup.connect(url).userAgent("Mozilla/5.0 (Windows NT 6.1; rv:5.0)").timeout(timeout).get();
			}catch(Exception e){
				e.printStackTrace();
 
			}
		}
		return doc;
	}
 
	public static void writefile(String txtstr)throws Exception{
		File txtpath=new File(txtpathstr);
		if (!txtpath.exists()){
			txtpath.mkdirs();
		}
		File htxt=new File(txtpathstr+"test.txt");
		BufferedOutputStream outBuff = new BufferedOutputStream(new FileOutputStream(htxt));
		outBuff.write(txtstr.getBytes());
		outBuff.flush();
		outBuff.close();
	}
 
}

　　

存在问题：只能一次性读取出来，不能按照要求，按照table分开，下一版本会解决这个问题
