正则表达式中的多行和非贪婪模式

多行就是在前边加"(?s)"

非贪婪模式就是在*、？、+ 后边再加？

例子：

URL url = new URL("http://money.finance.sina.com.cn/corp/go.php/vMS_MarketHistory/stockid/600000.phtml");
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] arr = new byte[1024];
int len = -1;
while((len = is.read(arr)) > 0) {
    out.write(arr);
}
String content = out.toString("GBK");
System.out.println(content);

String regstr = "(?s)<a target='_blank'\s+href='http://vip.stock.finance.sina.com.cn/quotes_service/view/vMS_tradehistory.php\?symbol=\w{2}\d{6}&date=\d{4}-\d{2}-\d{2}'>"
+ "\s+(\d{4}-\d{2}-\d{2})\s+.*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+"
+ "<td[^\d]*([^<]*).*?</td>\s+";

Pattern p = Pattern.compile(regstr);
Matcher m = p.matcher(content);
while(m.find()){
    System.out.println(m.group());
    System.out.println(m.group(1));
    System.out.println(m.group(2));
    System.out.println(m.group(3));
    System.out.println(m.group(4));
    System.out.println(m.group(5));
    System.out.println(m.group(6));
    System.out.println(m.group(7));
}
                
//System.out.println(content);
} catch (IOException e) {
// TODO Auto-generated catch block
    e.printStackTrace();
}
