我想用一个正则表达式字符串中一个特定的词后，立刻找到这个词。例如，如果单词是我的'，

I want to find the word immediately after a particular word in a string using a regex. For example, if the word is 'my',

这是我的祈祷 - 祈祷

"This is my prayer"- prayer

这是我的书（） - 书

"this is my book()"- book

是否有可能使用正则表达式？

Is it possible using regex?

\p{L}+ is a sequence of letters. The \p{L} is a Unicode code point with the property "Letter", so it matches a letter in any language.

（小于？= \ BMY \ S +）是向后断言，确保之前

(?<=\bmy\s+) is a lookbehind assertion, that ensures thet word "my" is before
