  		String a = "<li><a href=\"?bid=2&did=0&eid=1227\">高速路上停车捡葫芦引发交通事故一人身亡</a><span>2013-09-29</span></li>";
  		
  		Pattern p = Pattern.compile("<li><a href=\"([^\"]*)\"[^>?]*>([^<]*)</a><span>([^<]*)</span></li>",Pattern.DOTALL);
  		
  		Matcher matcher = p.matcher(a);	
  		
  		if(matcher.find()){
  			System.out.println(matcher.group(1));
  			System.out.println(matcher.group(2));
  			System.out.println(matcher.group(3));
  		}

Pattern p = Pattern.compile (" (. +?) (. +?) ");
Matcher m = p.matcher (str);
while (m.find ()) {
n.setNews_Rq (m.group (3));
n.setNews_Title (m.group (2). replace (""", " \ " " ) ) ;
n.setNews_Url (m.group (1). replace ("\" ", ; " " ) ) ;
n.setNews_Id (n.getNews_Id () +1); ;
}

newsService.save (n);
This is what I wrote it myself, my definition of news_rq is date type , so did not get ah
