标准表达式匹配 [英] regalar expression match

问题描述

Regex的新手，我很难搞清楚这个。


我需要一个基于平衡方括号的正则表达式。

例如：

[$ AA [123]]，[BB [bb]，CC]，[a [b [c]]]


我正在尝试编写一个将上述内容分解为3个部分的注册表：

1）[$ AA [123]]（或$ AA [123]没问题）

2）[BB [bb]，CC]

3）[a [b [c]]]


基本上，任何时候方括号平衡，我希望能够把这个价值拿出来。


我写道:(？< column> \ [ （[^ \ [\]] *（\ [。* \]）*）* \]）


基本上，找一个[，然后重复拿非和和非]

字符或者找到一个内部的[...]并取出它们之间的所有内容;

直到你点击一个]。这是后来的部分，因为我看起来不行，

弄清楚如何让括号正确平衡。这只是

正则表达式的意思吗？感谢您的帮助。

New to Regex and I''m having a hard time figuring this one out.

I need a regular expression what will based on balanced square brackets.
For example:
[$AA[123]], [BB[bb],CC], [a[b[c]]]

I''m trying to write a reg ex that will parse the above into 3 pieces:
1) [$AA[123]] (or $AA[123] would be fine)
2) [BB[bb],CC]
3) [a[b[c]]]

Basically, any time the square brackets balance, I want to be able to pluck
out that value.

I wrote: (?<column>\[([^\[\]]*(\[.*\])*)*\])

Basically, look for a [, then repeatly take either a non-"[" and non-"]"
character or find an internal set of [...] and take everything between them;
until you hit a ]. It''s the later part that doesn''t work as I can''t seem to
figure out how to get the brackets to balance properly. Is this just
something regular expression are not meant to do? Thanks for any help.
