How can I create a regex that matches a string contains a word from one list AND does not contains word from another list?
如何创建一个与字符串匹配的regex，该字符串包含一个列表中的单词，而不包含另一个列表中的单词？
我想创建一个regex，它匹配一个包含以下任何单词(fox，cat)且不包含(red，black)的字符串。
前任：
The quick brown fox jumps over the lazy dog --- match
The quick red fox jumps over the lazy dog ---- no match
The quick brown lion jumps over the lazy cat---- match
The quick black cat jumps over the lazy dog ---- no match
