Question

I have a string that looks like below, and I have to remove everything between the first bracket and the last bracket. All bets are off, on what’s in between (regarding other brackets). What would be the best aproach, thanks.

'[

        { "foo":
            {"bar":"foo",
                "bar": {
                    ["foo":"bar", "foo":"bar"]
                }
            }
        }

    ],

"foo":"bar","foo":"bar"'

result:

  ',

    "foo":"bar","foo":"bar"'

If your data really does look like that and you don’t have an brackets in the bit at the end then:

s.gsub(/\[.*\]/m, '')

If you want to be a little more paranoid, then you can look for ], followed by an end-of-line:

s.gsub(/\[.*\],$/m, ',')

Hard to say any more than that without a specification of your data format.
