正则表达式如何匹配多组格式相同的数据

Question

例:
"
start
a:123123
b:123456789
c:123456
/over
start
d:123123
e:123456789
f:123456
/over"
就像上边的例子一样,我要匹配出start至/over的内容
但是
如果用"^start[]{*}/over"这样匹配的话,
我就得到了
"
start
a:123123
b:123456789
c:123456
/over
start
d:123123
e:123456789
f:123456
/over"
,哪位大侠帮帮忙啊

试试这个，不过我假定你的第一行XOL 2.6.0063017a 20100703Serial C JX000000不会改变        static void Main(string[] args)
        {
            string src = @"XOL 2.6.0063017a 20100703Serial C JX000000

/WBE2009572559";
            foreach (Match m in Regex.Matches(src, @"XOL 2.6.0063017a 20100703Serial C JX000000[\W\w]([\W\w]*?)/WBE\d{10}", RegexOptions.Multiline))
