If given (TEXT)testest (GOPHER)mytest (TAG)(not_this)
,
I want to grep only the first occurrence of characters inside parentheses.
The regex results need to be TEXT
, GOPHER
, TAG
, but NOT not_this
because this is not the first occurrence in that word phrase. And the grepped text should be only letters not numbers.
regexp.MustCompile(`(?i)\([a-z0-9_-])+\]`)
// is not working
How do I write the regular expression to grep this? Thank you in advance!
