使用正则表达式捕获文本中的大写单词

Question

I'm trying to find words that are in uppercase in a given piece of text. The words must be one after the other to be considered and they must be at least 4 of them.

I have a "almost" working code but it captures much more: [A-Z]*(?: +[A-Z]*){4,}. The capture group also includes spaces at the start or the end of those words (like a boundary).

I have a playground if you want to test it out: https://regex101.com/r/BmXHFP/2

Is there a way to make the regex in example capture only the words in the first sentence? The language I'm using is Go and it has no look-behind/ahead.

Answer 1

In your regex, you just need to change the second * for a +:

[A-Z]*(?: +[A-Z]+){4,}

Explanation

While using (?: +[A-Z]*), you are matchin "a space followed by 0+ letters". So you are matching spaces. When replacing the * by a +, you matches spaces if there are uppercase after.
