拆分字符串包含html标记

问题描述

我有这个html字符串：

this simple the<b>html string</b> text test that<b>need</b>to<b>spl</b>it it too

我想将其拆分成这样的结果数组：

this simple 
the<b>html string<b>
text test 
that<b>need</b>to<b>spl</b>it
it too

我尝试过这种方式：

     var string ='this simple the<b>html string</b> text test that<b>need</b>to<b>spl</b>it it too';
     var regex =  XRegExp('((?:[\\p{L}\\p{Mn}]+|)<\\s*.*?[^>]*>.*?<\/.*?>(?:[\\p{L}\\p{Mn}]+|))',"g");
 
    result = string.split(regex);

没有用，我不想逐字分割...

解决方法

使用

string.split(/\s*(?<!\S)([^\s<>]+(?:\s+[^\s<>]+)*)(?!\S)\s*/).filter(Boolean);

捕获组将使您可以将匹配项保存为结果数组的一部分。

正则表达式

JavaScript：

const string = 'this simple the<b>html string</b> text test that<b>need</b>to<b>spl</b>it it too';
const regex= /\s*(?<!\S)([^\s<>]+(?:\s+[^\s<>]+)*)(?!\S)\s*/;
console.log(string.split(regex).filter(Boolean));

输出：

[
  "this simple","the<b>html string</b>","text test","that<b>need</b>to<b>spl</b>it","it too"
]
