正则表达式根据连字符的出现情况来匹配句子中单词中的连字符
我正在尝试匹配单词中的连字符，但前提是连字符在该单词中出现多次，
因此在短语“Step-By-Step”中连字符将被匹配，而在短语“Coca-Cola”中，连字符将被匹配连字符将不匹配。
在组合短语“Step-By-Step and Coca-Cola”的完整句子中，只有“Step-By-Step”中的连字符才会匹配。
我当前有以下表达式，但是这匹配所有由非数字字符分隔的连字符，无论出现什么情况，
((?=\D)-(?<=\D))
我似乎无法让量词与该表达式一起使用，有什么想法吗？
I am trying to match on hyphens in a word but only if the hyphen occurs in said word say more than once
So in the phrase "Step-By-Step" the hyphens would be matched whereas in the phrase "Coca-Cola", the hyphens would not be matched.
In a full sentence combining phrases "Step-By-Step and Coca-Cola" only the hyphens within "Step-By-Step" would be expected to match.
I have the following expression currently, but this is matching all hyphens separated by non-digit characters regardless of occurences
((?=\D)-(?<=\D))
I can't seem to get the quantifiers to work with this expression, any ideas?

Here is a way to match all hyphens in a line with more than one hyphen in PCRE:
RegEx Demo
Explanation:
[^\s-]*matches a character that is not a whitespace and not a hyphen(?=(?:[^\s-]*-){2})is lookahead to make sure there are at least 2 hyphens in a non-whitespace substring\Gasserts position at the end of the previous match or the start of the string for the first match\Kresets match info这至少匹配两个单词，每个单词后跟连字符，后跟另一个单词（我假设您不想在开头或结尾允许连字符，仅在单词之间使用）。
This matches at least two words each followed by hyphen, followed by another word (I'm assuming you don't want to allow hyphen at the very beginning or end, only between words).
