/[a-zA-Z/]+$
如果要把第一个斜杠去掉,就是匹配index/index/index,用后向匹配,正则是:
(?=/)[a-zA-Z/]+$
@interface不替换的话,就把正则改成:
@(?!interface)[^\s]+(\s|$)
如果@t3(synopsis = "AB") 这个等号前后没有空格,就很简单,直接用下面的搞定,如果有空格,这个正则就会复杂很多了:
Regex.Replace(@"@t1
@t2()
@t3(synopsis=""AB"")
@t4(""unused"")
creatCommChat(@WebParam(name=""chatID"") String chatID,@WebParam(name=""creatUserID"") String creatUserID)", @"@[^\s]+(\s|$)", "")
groups(1)就是匹配项的第一个捕获组(注:groups(0)就是匹配项本身),也就是你上面括号里的内容,也就是sector后面的数字,但你这样写应该匹配不到内容吧,大小写都不一样,另外还有换行的问题。
var reg = /;SPLIT(?:(?!;SPLIT)[\s\S])*;SPLIT/g;
var str = "";
str.replace(reg,"");

如图:
Matches[1] 就是cc的数字
Matches[2] 就是bb的数字
[0]是整个字符串
