我随机存储了文字$sentences.使用正则表达式,我想将文本拆分成句子,请参阅:

function splitSentences($text) {
    $re = '/                # Split sentences on whitespace between them.
        (?<=                # Begin positive lookbehind.
          [.!?]             # Either an end of sentence punct,
        | [.!?][\'"]        # or end of sentence punct and quote.
        )                   # End positive lookbehind.
        (?<!                # Begin negative lookbehind.
          Mr\.              # Skip either "Mr."
        | Mrs\.             # or "Mrs.",
        | T\.V\.A\.         # or "T.V.A.",
                            # or... (you get the idea).
        )                   # End negative lookbehind.
        \s+                 # Split on whitespace …

所以这是字符串s:

"Hi! How are you? I'm fine. It is 6 p.m. Thank you! That's it."

我希望它们被分隔为一个数组:

["Hi", "How are you", "I'm fine", "It is 6 p.m", "Thank you", "That's it"]

这意味着分隔符应为". "+ "? "+"! "

我试过了:

let charSet = NSCharacterSet(charactersInString: ".?!")
let array = s.componentsSeparatedByCharactersInSet(charSet)

但它也将分为p.m.两个元素.结果:

["Hi", " How are you", " I'm fine", " It is 6 p", "m", " Thank you", " That's it"]

我也试过了

let array = s.componentsSeparatedByString(". ") …
