I'm trying to extract variable names from a large block of text. The variables are identified by 2 opening and closing brackets [[varname]]. The problem is that some of the variables are references to an index in an array [[varname[0]]].
I've tried \\[{2}(.+?)\\]{2,}
. The matched text for the array vars is correct, but the text in the captured group is missing the trailing bracket. For example, in the string:
"This is an array var [[arrayvar[0]]]"
I'm trying to match [[arrayvar[0]]]
get out arrayvar[0]
via the group.
Here's an example of what I'm trying to do https://regex101.com/r/lH1zQ0/4
Any ideas?
