Question

你们有人可以帮帮我吗？我将字符串下载到“结果”，如下所示：

DrawDate,Ball 1,Ball 2,Ball 3,Ball 4,Ball 5,Ball 6,Bonus Ball,Ball Set,Machine27-Feb-2013,2,24,14,23,20,30,22,6,MERLIN23-Feb-2013,31,25,32,2,30,16,36,5,MERLIN20-Feb-2013,36,45,3,6,44,48,47,8,MERLIN16-Feb-2013,7,27,48,46,39,20,49,6,ARTHUR13-Feb-2013,6,49,23,29,14,20,48,8,MERLIN09-Feb-2013,10,8,34,40,27,41,48,7,MERLIN06-Feb-2013,9,18,10,16,27,42,43,6,ARTHUR02-Feb-2013,2,13,14,21,12,30,39,7,ARTHUR30-Jan-2013,10,9,43,48,47,24,5,5,ARTHUR26-Jan-2013,2,6,21,29,47,34,11,5,ARTHUR

然后使用下面的正则表达式：

Pattern p = Pattern.compile("(Machine|GUINEVERE|LANCELOT|ARTHUR|MERLIN)(.*?)(GUINEVERE|LANCELOT|ARTHUR|MERLIN)"); 

Matcher m = p.matcher(result);

while (m.find())
{
matchesList.add(m.group()); 
}

这是我的列表视图：

1, Machine27-Feb-2013,2,24,14,23,20,30,22,6,LANCELOT

2, MERLIN20-Feb-2013,36,45,3,6,44,48,47,8,GUINEVER

3, ARTHUR13-Feb-2013,6,49,23,29,14,20,48,8,MERLIN

但正则表达式错过了每一个偶数行：

1, Machine27-Feb-2013,2,24,14,23,20,30,22,6,LANCELOT

2, 23-Feb-2013,31,25,32,2,30,16,36,5,

3, MERLIN20-Feb-2013,36,45,3,6,44,48,47,8,GUINEVER

4, 16-Feb-2013,7,27,48,46,39,20,49,6,

5, ARTHUR13-Feb-2013,6,49,23,29,14,20,48,8,MERLIN

6, 09-Feb-2013,10,8,34,40,27,41,48,7,

这就是我所追求的：

1, 27-Feb-2013,2,24,14,23,20,30,22,6

2, 23-Feb-2013,31,25,32,2,30,16,36,5

3, 20-Feb-2013,36,45,3,6,44,48,47,8

4, 16-Feb-2013,7,27,48,46,39,20,49,6

5, 13-Feb-2013,6,49,23,29,14,20,48,8

6, 09-Feb-2013,10,8,34,40,27,41,48,7

中的不

我已尝试从网络到无效的各种方式。试过 ^ 和 $ ，但不明白怎么工作？

Answer 1

正则表达式的“（机器| GUINEVERE | ...）”部分是捕获组。这意味着（1）它们包含在结果中，（2）以下匹配在之后开始。

正则表达式在多场比赛中
