javascript - 如何编写此正则表达式以获取多行数据并转换为 JSON 数组

Question

我有一些数据需要转换为数组，但我无法让正则表达式正常工作。我只需要一个一维数组，不需要数字，只需要值 - 但是带有换行符的项目把它搞砸了。

正则表达式:([0-9]\-\ )(.*)([\s]*)
测试:https://regex101.com/r/F9UIG8/1

数据:

1- TEST DATA.
   1- TEST DATA THAT GOES ONTO
      TWO LINES.
   2- MORE TESTS.
      1- ADDITIONAL MULTILINE 
         DATA WITH 
         SEVERAL LINES
   3- MORE TEST 3
   4- MORE TEST 4
      1- MORE SUB ITEMS
      2- SUB ITEM 2
      3- SUB ITEM MULTILINE
         SECOND LINE
      4- MORE
2- EVEN MORE TWO LINE
   SECOND LINE
   1- DATA
   2- DATA
   3- DATA
   4- DATA TWO LINE
      2ND LINE.
3- LAST BIT OF 2 LINE DATA
   WITH SECOND LINE

Answer 1

用 split() 试试这个正则表达式方法:

let text =  `1- TEST DATA.
   1- TEST DATA THAT GOES ONTO
      TWO LINES.
   2- MORE TESTS.
      1- ADDITIONAL MULTILINE
         DATA WITH
         SEVERAL LINES
   3- MORE TEST 3
   4- MORE TEST 4
      1- MORE SUB ITEMS
      2- SUB ITEM 2
      3- SUB ITEM MULTILINE
         SECOND LINE
      4- MORE
2- EVEN MORE TWO LINE
   SECOND LINE
   1- DATA
   2- DATA
   3- DATA
   4- DATA TWO LINE
      2ND LINE.
3- LAST BIT OF 2 LINE DATA`;

text.split(/\s*\d\-/igm);

它将返回一个包含文本(包括换行符)的数组，删除数字和连字符。
