java字符串拆分所有非字母数字除撇号 [英] java string split on all non-alphanumeric except apostrophes

问题描述

所以我想在任何非字母数字字符上拆分java中的字符串。

So I want to split a string in java on any non-alphanumeric characters.

目前我一直在这样做

words= Str.split("\\W+");

但是我想在那里保留撇号（'）。是否有任何正则表达式来保留撇号但踢掉其余的垃圾？谢谢。

However I want to keep apostrophes("'") in there. Is there any regular expression to preserve apostrophes but kick the rest of the junk? Thanks.

推荐答案

words = Str.split("[^\\w']+");

只需将其添加到角色类。 \ W 相当于 [^ \w] ，然后您可以添加 ' to。

Just add it to the character class. \W is equivalent to [^\w], which you can then add ' to.

请注意， \w 实际上也包括下划线。如果你想在下划线上拆分，你应该使用 [^ a-zA-Z0-9'] 代替。

Do note, however, that \w also actually includes underscores. If you want to split on underscores as well, you should be using [^a-zA-Z0-9'] instead.
