如何使用正则表达式查找包含某个字母的单词? [英] How to find words containing a certain letter with Regular Expressions?

问题描述

我需要一个正则表达式来查找包含字母y"的任何单词.

I need a regular expression to find any words containing the letter "y".

这是我的想法:

/\bw*[y]\w*\b/

词边界，有或无，y，有或无，词边界.
它适用于第一个单词，但不适用于下一个.

a word boundary, something or nothing, y, something or nothing, word boundary.
It works for the first word, but not for the next one.

如何获取字符串中包含 y 的所有单词?

How do I get all the words containing a y within a string?

推荐答案

不知道您使用的是什么语言并根据您尝试的语法猜测，这应该有效:

Not knowing what language you're using and guessing based on the syntax of your attempt, this should work:

/\b\w*[Yy]\w*\b/g

如果没有 "g"(用于全局")选项获得第一场比赛.另请注意，这与大写和小写的y"匹配.

Without the "g" (for "global") option you'll only get the first match. Note also this matches on "y" in both upper and lower case.
