我提出我的申请将获得的两种可能的细微投入,如果与以下两条插图相匹配,我需要加以分类,以恢复:
"User * has logged out"
"User * has joined"
我不喜欢reg,而只是想说明如何实现上述目标。
任何帮助都是巨大的!
假设你意欲将<代码>*字面上作为星号加以匹配,那么,你需要先用<代码><>/代码>填写。
@"> 用户* (略微)
如果通过<代码>*,你指“任何用户名称”,则代之以您为验证用户名称而使用的密码,或因缺乏任何更好的信息,你总是只能使用<代码>*。
<代码>(挂号:建筑称为“硬化”。 周围的括号除在本案中强制规定交替优先外,还把载于第1组的“座标”()”或“joined”),视其不同之处而定。
如果你不需要区分这两种事件,那么你实际上就不需要这种扼杀,而且你可以使用一个没有捕获的组群(<条码>(?: 缩略语),以便稍微提高业绩。
^ and $ are what are打脚石, which they they have been used and end of the string. 适当将这些根基置于模式中,可确保它与整个投入结构相匹配,而不仅仅是一个子体。
* 假定为用户名称:
"User .+ has (joined|logged out)"
或者也许像这种情况(用户名称可能需要更多的特性选择):
"User [A-Za-z0-1_]+ has (joined|logged out)"
