Question

大家好，这是我下面的身体。基本上每个块都由一条没有任何东西的线分隔。每个块都有一个括号中的标题，然后可以有左边的单词格式的任意数量的属性，然后等于，然后是右边的单词。

[General]
StartWithLastProfile=0

[Profile0]
Name=default
IsRelative=1
Path=Profiles/vr10qb8s.default
Default=1

[Profile1]
Name=cleanER One Here
IsRelative=1
Path=Profiles/k46wtieb.cleanER One Here

我正在尝试获得3场比赛。每个应该看起来像：[整个匹配，标题，prop1，val1，propN，valN]

匹配1：

['[General]
StartWithLastProfile=0','General','StartWithLastProfile','0']

MATCH2：

['[Profile0]
Name=default
IsRelative=1
Path=Profiles/vr10qb8s.default
Default=1','Profile0','Name','default','IsRelative','1','Path','Profiles/vr10qb8s.default','Default','1']

等等。

所以这是我的正则表达式：

       var patt = /\[.*\](?:\s+?([\S]+)=([\S]+)+/mg;
       var blocks = [];

       var match;
       while (match = patt.exec(readStr)) {
        console.log(match)
       }

但这是吐出来的：[整场比赛，冠军，预言，valLAST]; 如果我将正则表达式中的最后一个+更改为+？然后它给了 [全场比赛，冠军，道具，valFIRST];

这个正则表达式有效，但有一个噱头：

var patt = /\[.*\](?:\s+?([\S]+)=([\S]+))(?:\s+?([\S]+)=([\S]+))?(?:\s+?([\S]+)=([\S]+))?(?:\s+?([\S]+)=([\S]+))?(?:\s+?([\S]+)=([\S]+))?/mg;

现在返回：

[ "[General]
StartWithLastProfile=0", "StartWithLastProfile", "0", undefined, undefined, undefined, undefined, undefined, undefined, undefined, 1 more… ]

[ "[Profile0]
Name=default
IsRelative=1
Path=Profiles/vr10qb8s.default
Default=1", "Name", "default", "IsRelative", "1", "Path", "Profiles/vr10qb8s.default", "Default", "1", undefined, 1 more… ]

[ "[Profile1]
Name=cleanER
IsRelative=1
Path=Profiles/k46wtieb.clean", "Name", "cleanER", "IsRelative", "1", "Path", "Profiles/k46wtieb.clean", undefined, undefined, undefined, 1 more… ]

我最后不想要那些不必要的未定义，这种模式仅限于模式末尾的(?:\s+?([\S]+)=([\S]+))?我粘贴的数量

请帮助

JavaScript代码

string = string.split(/\n\n/g); // split along the double newline to get blocks

var matches = [];  // the complete matches array has `match1`, `match2`, etc.

string.forEach(function(elem, index){ // for each block
  var matchArr = [];               // make a matchArr

  matchArr.push(elem); // wholeMatch 

  elem.replace(/\[([a-z0-9]+)\]/i, function(match, $1){    
    matchArr.push($1); // get the title  
  });

  elem.replace(/([a-z]+)=(.+)/ig, function(match, $1, $2){
    matchArr.push($1); // property
    matchArr.push($2); // value
  });

  matches.push(matchArr);  // push the `match` in bigger `matches` array
});

console.log(matches); // get the whole matches array

// You can use `matches[0]` to get the 1st match, and so on.

希望有所帮助！
