正则表达式匹配不在分组符号之间的逗号

发布于 2024-11-09 11:56:08 字数 447 浏览 3 评论 0原文

我需要一个正则表达式来匹配不在“[”和“]”或“(”和“)”或“{”和“}”之间的逗号。其他分组符号并不重要。我试图弄清楚这一点，但我想不出任何可以实现这一目标的方法。

正则表达式与 PHP preg_split 函数一起使用，以匹配的逗号分割字符串。

包含逗号和分组符号的示例字符串：

<div>Hello<div>,@func[opt1,opt2],{,test},blahblah

该字符串应拆分如下：

1: '<div>Hello<div>'
2: '@func[opt1,opt2]'
3: '{,test}'
4: 'blahblah'

我只是想到了这一点，但此时所有分组符号都保证具有匹配的符号，以防有帮助。

任何帮助将非常感激 =)

I need a regular expression that will match a comma that is NOT between either a '[' and ']' or '(' and ')' or '{' and '}'. Other grouping symbols do not matter. I have tried to figure it out but I cannot come up with anything that accomplishes this.

The regex is to be used with the PHP preg_split function to split a string on the matched commas.

An example string containing commas and grouping symbols:

<div>Hello<div>,@func[opt1,opt2],{,test},blahblah

The string should split up as follows:

1: '<div>Hello<div>'
2: '@func[opt1,opt2]'
3: '{,test}'
4: 'blahblah'

And I just thought of this, but at this point all grouping symbols are guaranteed to have matching symbols, incase that helps.

Any help would be GREATLY appriciated =)

其实这种拆分也不是不可能的。考虑这段代码：

$str = '<div>Hello<div>,(foo,bar),@func[opt1,opt2],{,test},blahblah';
$arr = preg_split('~([^,]*(?:{[^}]*}|\([^)]*\)|\[[^]]*])[^,]*)+|,~', $str, -1 , PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
var_dump($arr);

输出：

array(5) {
  [0]=>
  string(15) "<div>Hello<div>"
  [1]=>
  string(9) "(foo,bar)"
  [2]=>
  string(16) "@func[opt1,opt2]"
  [3]=>
  string(7) "{,test}"
  [4]=>
  string(8) "blahblah"
}

Actually it is not impossible to get this splitting done. Consider this code:

$str = '<div>Hello<div>,(foo,bar),@func[opt1,opt2],{,test},blahblah';
$arr = preg_split('~([^,]*(?:{[^}]*}|\([^)]*\)|\[[^]]*])[^,]*)+|,~', $str, -1 , PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
var_dump($arr);

OUTPUT:

array(5) {
  [0]=>
  string(15) "<div>Hello<div>"
  [1]=>
  string(9) "(foo,bar)"
  [2]=>
  string(16) "@func[opt1,opt2]"
  [3]=>
  string(7) "{,test}"
  [4]=>
  string(8) "blahblah"
}
