[英]Regex - match a string, but only where the next word is not 'x'
If I have this string: 如果我有这个字符串:
"The quick brown fox jumped over the lazy dog. What a nice brown fox that is." “快速的棕色狐狸跳过懒狗。真是个漂亮的棕色狐狸。”
What regex would I use to match the text 'brown fox' but not where the following word is 'that', ie (matches in italic): 我将使用什么正则表达式匹配文本'棕色狐狸',而不是下面的单词是'那',即(匹配斜体):
"The quick brown fox jumped over the lazy dog. What a nice brown fox that is." “快速的棕色狐狸跳过懒狗。真是个漂亮的棕色狐狸。”
你需要一个零宽度的负前瞻断言 ,即
brown fox(?! that)
