Objective c Objc Regex-使用组解析字符串

我试图在“：”之前和之后解析文本文件和组信息，这样我就可以知道什么与什么相关

我正在使用下面的

//NSString *pattern = @"\\[(.*?)\\]"; //[]
//NSString *pattern = @"(\\w+:)"; //word:
NSString *pattern =@"(\\w+:)\\[(.*?)\\]";
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:pattern options:NSRegularExpressionCaseInsensitive error:nil];
NSString *input = contents; //contents being the value taken from the text file

NSMutableArray *matches = [NSMutableArray arrayWithCapacity:[myArray count]];
for (NSTextCheckingResult *match in myArray) {
    //NSUInteger numberOfRanges = [match numberOfRanges];
    //NSLog(@"%lu", (unsigned long)numberOfRanges);
    NSRange matchRange = [match rangeAtIndex:1];
    [matches addObject:[input substringWithRange:matchRange]];
    NSLog(@"%@", [matches lastObject]);
}

“[]”和“单词：”起作用，但当我把它们连在一起时，我什么也得不到

括号（输出）

字（输出）

我在模式中遗漏了什么

NSString *pattern =@"(\\w+:)\\[(.*?)\\]";

数据就是一个例子

由于您需要将每个“单词”与其对应的

[…]

进行匹配，因此可以使用包含2个捕获组的正则表达式模式和将“调节”惰性点匹配模式的前瞻：

@"(?s)(\\w+):\\s*\\[(.*?)\\](?=,\r?\n\\s*\\w+:|$)"

见

模式匹配：

• （？s）

  -启用
  以匹配换行符

• （\w+）：

  -将一个或多个字母数字字符匹配并捕获到组1中，然后匹配

  ：

• \s*

  -0+空格字符

• \[（.*）\]

  -匹配

  […]

  捕获组1中的所有内容（如果最后一个

  ]

• （？=，\r？\n\s*\w+：|$）

  -后跟字符串结尾（

  $

  ），或逗号后跟换行符，后跟0+空格符号，后跟“word”，后跟

  ：

不太清楚。也许你需要？谢谢@WiktorStribiżew，这是4个单独的匹配。这是否意味着你在寻找这个解决方案？我理想情况下想要所有的东西：在一场比赛之前，在一场比赛之后：在一场比赛中，所以我会有四个部分中的每一个，然后每个部分两组
