解析来自 API 的文本并转换为对象

Question

I'm reading data from a text file which looks something like this:

#start
#p 09060 20131010
#p 09180 AK
#p 01001 19110212982
#end
#start
#p 09060 20131110
#p 09180 AB
#p 01001 12110212982
#end

Parsing it to an object:

var result = data.match(/#start[\s\S]+?#end/ig).map(function(v){

    var lines = v.split('\n'),
        ret = {};

    $.each(lines, function(_, v2){
        var split = v2.split(' ');
        if(split[1] && split[2]) 
            ret[split[1]] = split[2];
    });

    return ret;
});

This would give me a list of objects which looks something like:

[{ 09060: 20131010, 09180: 'AK' }, { 09060: 20131110, 09180: 'AB' }] //etc...

However, I've noticed that each entry contains duplicates, which would cause my method to overwrite the properties:

#start
#p 09060 20131110
#p 09180 AB
#p 01001 12110212982
#p 20000
#p 20001 ABC
#p 20002 123
#p 29999
#p 20000
#p 20001 CDE
#p 20002 345
#p 29999
#end

I would like to hear your ideas how to handle this. My first thought is to identify "chunks" and create lists when they appear, and create a property like:

{ 
    09060: 20131010, 
    09180: 'AK',
    20000_29999: [
        { 20001: 'ABC', 20002: 123 }, { 20001: 'CDE', 20002: 456 }
    ]
}

I'm not sure how do identify the "chunks" in the loop, without specifying the keys ( 20000 and 29999 in this case).

Do you guys have any suggestions?

Answer 1

Use an array to hold the values.

var result = data.match(/#start[\s\S]+?#end/ig).map(function(v){

    var lines = v.split('\n'),
        ret = {};

    $.each(lines, function(_, v2){
        var split = v2.split(' ');
        if(split[1] && split[2]) {
           // use array to hold values
           ret[split[1]] ||= [];
           ret[split[1]].push(split[2]);
        }      
    });

    return ret;
});

Answer 2

I wonder how will you use this object, you can use the following structures:

[
  {
    "20001": [
      "ABC",
      "CDE"
    ],
    "09060": "20131110"
  },
  {
    "20001": [
      "ABC",
      "CDE"
    ],
    "09060": "20131110"
  }
]

OR

[
  {
    "20001": {
      "ABC": 1,
      "CDE": 1
    },
    "09060": "20131110"
  },
  {
    "20001": {
      "ABC": 1,
      "CDE": 1
    },
    "09060": "20131110"
  }
]

OR

[
  [
    [
      "20001",
      "ABC"
    ],
    [
      "20001",
      "CDE"
    ],
    [
      "09060",
      "20131110"
    ]
  ],
  [
    [
      "20001",
      "ABC"
    ],
    [
      "20001",
      "CDE"
    ],
    [
      "09060",
      "20131110"
    ]
  ]
]
