定期表达:积极的 Look头和口头边界问题
原标题:Regular Expressions: Positive Lookahead and Word Border question

Hello 再度来到圣塔多里。

认为我有这些话:讲聪明语、讲聪明语

我想从内部调取“电话”。 然而,在这两种情况下,我只希望“电话”返回,而不是“电话”。 除此以外,我只想说“电话”一词只够了,这样:

fonephonetics (just an example) is notcomped.

我假定该区

(phone([?=s])?)

我会给我提供我所需要的东西,但是,它目前正在对“电话”和“电话”进行匹配,而不是将“声音”同起来。 我不需要“电话”。 我想对这两起案件说“电话”。

任何关于什么错和我能做什么的想法?

事先感谢你!

最佳回答

匹配<条码> 之后是s:

phone(?=s?)

头盔为零宽度,因此,s作为配对的一部分退还。
