正则表达式获取两个字符串之间的字符串

Question

我有这个字符串:

# userid name uniqueid connected ping loss state rate
# 529 2 "arioch83" STEAM_1:0:86796179 55:58 99 0 active 80000
# 619 3 "Snake" STEAM_1:0:27678629 06:42 61 0 active 80000
# 622 4 "Captain_Selleri" STEAM_1:1:47927314 03:25 44 0 active 80000
# 583 5 "krN[786]" STEAM_1:1:14638235 28:53 53 0 active 128000
# 621 6 "Giack" STEAM_1:1:67468100 04:44 129 0 active 80000
# 326 7 "Urkrass" STEAM_1:0:55150382  3:02:31 51 0 active 80000
#613 "Vinny" BOT active
# 584 9 "Tkappa" STEAM_1:0:32266787 27:55 360 0 active 80000
# 605 10 "Narpok19" STEAM_1:0:44838130 14:36 67 0 active 80000
# 551 11 "robbetto83" STEAM_1:1:63675894 50:10 86 0 active 80000
# 530 12 "XxKazuyaxX" STEAM_1:0:18676379 55:57 68 0 active 80000
# 623 13 "beut3d - Keyser Söze" STEAM_1:0:14500718 00:29 70 0 active 80000
# 602 15 "Homroy" STEAM_1:1:7870901 16:34 169 0 active 80000
# 607 16 "[Bloody]Eagle" STEAM_1:1:59567346 09:14 77 0 active 80000
#615 "Jeff" BOT active
# 587 18 "Heisenberg" STEAM_1:1:61427218 25:15 81 0 active 80000
#end

我想在"#userid name uniqueid connected ping loss state rate"和"#end"之间输入字符串.我尝试了几个正则表达式基于我在stackoverflow上找到但没有效果:(这是我的最后一次尝试

var matches = text.match(/# userid name uniqueid connected ping loss state rate(.+)\&#end/);
                if (matches.length > 1) {
                    alert(matches[1]);
                }

正如你所看到的,我对正则表达式一无所知......关于那些的任何好的tuto？

谢谢,

您需要能够跨多行匹配.您正在寻找s(dotall)修饰符.不幸的是,这个修饰符在JavaScript 中不存在.常见的解决方法是.使用以下内容替换点:

[\S\s]    

所以你可以使用以下正则表达式:

/# userid name uniqueid connected ping loss state rate([\S\s]*?)#end/

说明:

(               # group and capture to \1:
  [\S\s]*?      #   any character of: 
                #    non-whitespace (all but \n, \r, \t, \f, and " "), 
                #    whitespace (\n, \r, \t, \f, and " ") 
                #    (0 or more times matching the least amount possible)
)               # end of \1
