对于 ruby 中的给定场景，如何使用 gsub？

Question

I am giving the values as:

str = 'test["test1", "test2"]'

Using gsub , I want the value as '["test1", "test2"]' .

The condition is, the values before and after braces [ / ] should be removed.

Answer 1

This should remove anything before and after [ and ] :

str.gsub(/^[^\[]+/, '').gsub(/[^\]]+$/, '')

By parts:

> str = 'test["test`", "test2"]test'
 => "test[\"test`\", \"test2\"]test" 
> str.gsub(/^[^\[]+/, '')
 => "[\"test`\", \"test2\"]test" 
> str.gsub(/[^\]]+$/, '')
 => "test[\"test`\", \"test2\"]" 
> str.gsub(/^[^\[]+/, '').gsub(/[^\]]+$/, '')
 => "[\"test`\", \"test2\"]"
