正则表达式使用match()在单独的句子中拆分长文本 [英] Regex that splits long text in separate sentences with match()

问题描述

这是用户在其中写一些文本的文本区域.我已经在其中写了一个例子.

This is a textarea where the user writes some text. I've written an example in it.

<textarea id="text">First sentence. Second sentence? Third sentence!
Fourth sentence.

Fifth sentence
</textarea>

正则表达式中已考虑的要求

• 分隔符包含在数组项中
• 最后一句不一定需要使用分隔符(可以以任何字符结尾)
• 如果一个句子有多个分隔符，则它包含在数组项中.示例:第二句?！?应为[...，第二句?！?"，...]

• separator is included in array item
• last sentence doesn't necessarily require a separator character (it can end with any character)
• if a sentence has more than one separator char, it is included in the array item. Example: second sentence?!? should be [...,"second sentence?!?",...]

缺少的要求(我需要帮助)<<

每行都应由一个空数组项表示.如果应用了正则表达式，则应为以下响应:

Each new line should be represented by an empty array item. If the regex is applied, this should be the response:

["First sentence.", "Second sentence?", "Third sentence!", "", "Fourth sentence.", "", "", "Fifth sentence"]

相反，我收到此消息:

["First sentence.", "Second sentence?", "Third sentence!", "Fourth sentence.", "Fifth sentence"]

这是正则表达式和匹配项:

This is the regex and match call:

var tregex = /[^\r\n.!?]+(:?(:?\r\n|[\r\n]|[.!?])+|$)/gi;
var sentences = $('#text').val().match(tregex).map($.trim);

有什么想法吗?谢谢！

推荐答案

我将其简化了很多，要么匹配一行的结尾(换行)，要么匹配一个句子，然后加上标点符号:

I simplified it a lot, either match the end of a line (new line) or a sentence followed by punctuation:

var tregex = /\n|([^\r\n.!?]+([.!?]+|$))/gim;

我也相信多行的m标志很重要

I also believe the m flag for multiline is important
