我的正则表达式没有选择与内部文本最接近的’cont’对.我该如何解决这个问题?
输入:
cont cont ItextI /cont /cont
正则表达式:
cont.*?I(.*?)I.*?/cont
比赛:
cont cont ItextI /cont
匹配我需要:
cont ItextI /cont
cont(?:(?!/?cont).)*I(.*?)I(?:(?!/?cont).)*/cont
只会匹配最里面的块.
说明:
cont # match "cont" (?: # Match... (?!/?cont) # (as long as we're not at the start of "cont" or "/cont") . # any character. )* # Repeat any number of times. I # Match "I" (.*?) # Match as few characters as possible,capturing them. I # Match "I" (?: # Same as above (?!/?cont) . )* /cont # Match "/cont"
这明确禁止在开头的cont和要捕获的文本之间(以及在该文本和结束/续)之间出现cont或/ cont.
