如何在 Node.js 中使用我的 PHP 正则表达式？

Question

我在 PHP 中有一个正则表达式，但是当我将它移植到 Node.js 时，我得到的输出与我从 PHP 得到的输出不同，但我认为这是因为我真的不知道如何让 PREG_SET_ORDER 在 Node.js 中工作。

示例文本：

INPUT - Each line represents a line inside a text file. 
-------------------------------------------------------------------------------------
"!?Text" (1234)                                         1234-4321
"#1 Text" (1234)                                        1234-????
#2 Text (1234) {Some text (#1.1)}                       1234
Text (1234)                                             1234
Some Other Text: More Text here 1234-4321 (1234) (V)    1234

PHP:

preg_match_all("/^((.*?) *\((\d+)\))(?: *\{((.*?) *\((.+?)\)) *\})?/m",$data,$r, PREG_SET_ORDER);
$i = 0;
foreach($r as $a) {
    array_splice($a, 0, 2);
    if(count($a) > 2) {
        array_splice($a, 2, 1);
    }
    print_r($a);
}

Node.js:

var regex = /^((.*?) *\((\d+)\))(?: *\{((.*?) *\((.+?)\)) *\})?/mg
var result = data.toString().match(regex);
console.log(result);

PHP（输出）：

Array
(
    [0] => "!?Text"
    [1] => 1234
)
Array
(
    [0] => "#1 Text"
    [1] => 1234
)
Array
(
    [0] => #2 Text
    [1] => 1234
    [2] => Some text
    [3] => #1.1
)
Array
(
    [0] => Text
    [1] => 1234
)
Array
(
    [0] => Some Other Text: More Text here 1234-4321
    [1] => 1234
)

Node.js（输出）：

[ '"!?Text" (1234)',
  '"#1 Text" (1234)',
  '#2 Text (1234) {Some text (#1.1)}',
  'Text (1234)',
  'Some Other Text: More Text here 1234-4321 (1234)' ]

I managed to get it to work like this:

function data_to_array(data) {
   var regex = '^((.*?) *\((\d+)\))(?: *\{((.*?) *\((.+?)\)) *\})?';
   var Regex = new RegExp(regex, 'mg');
   var Matches = data.match(Regex);
   matchesArray = new Array();
   for (var i in Matches) {
      ngRegex = new RegExp(regex);
      ngMatches = Matches[i].match(ngRegex);
      ngMatches.splice(0, 2);
      if(ngMatches.length > 2) {
        ngMatches.splice(2, 1);
      }
      matchesArray.push(ngMatches);
   }
   return matchesArray;
}

var output = data_to_array(data.toString());
console.log(output);
