如何消除字符串列表的引号？

Question

我从文本文件中收到以下字符串列表：

[ “{0988070979，APP03 @媒体}”， “{0988070978，APP01 @媒体}”， “{0988070977，APP02 @媒体}”]

我需要相同的列表但没有引号（“”），如下所示：

[{0988070979，APP03 @媒体}，{0988070978，APP01 @媒体}，{0988070977，APP02 @媒体}]

Answer 1

您应该使用erl_scan模块tokenize字符串和erl_parse将令牌转换为erlang字词。

让你的字符串为Str

{ok, Ts, _} = erl_scan:string(Str).
{ok, Tup} = erl_parse:parse_term(Ts).

Tup是您需要的元组......

Answer 2

1> L = ["{0988070979,APP03@media}","{0988070978,APP01@media}","{0988070977,APP02@media}"].
["{0988070979,APP03@media}","{0988070978,APP01@media}",
 "{0988070977,APP02@media}"]
2> [{N, M} || X <- L, [N, M] <- [string:tokens(X, "{},")]].                               
[{"0988070979","APP03@media"},
 {"0988070978","APP01@media"},
 {"0988070977","APP02@media"}]

或（不推荐）

3> [{list_to_integer(N), list_to_atom(M)} || X <- L, [N, M] <- [string:tokens(X, "{},")]].                                                                    
[{988070979,'APP03@media'},
 {988070978,'APP01@media'},
 {988070977,'APP02@media'}]

等等。
