Question

我有一些数据需要转换为数组，但我无法使正则表达式工作得很好。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会弄乱它。

正则表达式：([0-9]\-\ )(.*)([\s]*)

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

使用split()方法尝试此正则表达式：

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);

它将返回一个带有文本的数组（包括换行符），删除数字和超量。

感谢您的帮助，我使用@ncardeli的答案变体将其构建到Google应用程序脚本中。

function JSONIFYRANGE(range, asJSON){
  var array = new Array();
  for (var i = 0; i < range.length; i++) {
    array.push({name: range[i][0], items: JSONIFY(range[i][1], asJSON)});
  }
  return JSON.stringify(array);
}

function JSONIFY(input, asJSON) {
  if(input.indexOf("[ ]") >= 0 || input.indexOf("[  ]") >= 0 || input.indexOf("[   ]") >= 0){
    return JSONIFY2(input, asJSON);
  } else {
    return JSONIFY1(input, asJSON);
  }
}

function JSONIFY1(input, asJSON) {
  var json = input.split(/\s*\d\-/igm); // answer from @ncardeli
  var newArray = new Array();
  for (var i = 0; i < json.length; i++) {
    if (json[i] != "") {
      newArray.push(json[i].replace("SOME COMMON TEXT I DONT WANT IN THE ITEMS", "").trim());                
    }
  }
  return asJSON ? newArray : JSON.stringify(newArray);
}

function JSONIFY2(input, asJSON) {
  var json = input.split(/\s*\[\s*\]/igm);
  var newArray = new Array();
  for (var i = 0; i < json.length; i++) {
    if (json[i] != "") {
      newArray.push(json[i].trim());
    }
  }
  return asJSON ? newArray : JSON.stringify(newArray);
}

使用它像：=JSONIFYRANGE('Items'!B2:C40, true)其中B列保存列表名称，C列保存要拆分为项目的字符串，输出带有以下签名的JSON字符串：

{[
  {
    name: "List 1 Name",
    items: [
      "TEST DATA THAT GOES INTO TWO LINES",
      "MORE TESTS.",
      ...
    ]
  },
  {
    name: "List 2 name",
    items: [
      "SOME ITEM",
      "SOME OTHER ITEM",
      ...
    ]
  },
  ...
]}
