Description

Grab all placeholder "tags" that are alphanumeric with optional underscores. In this example my placeholders are double curly braces e.g. {{MY_VARIABLE_NAME}}.

Change out the braces for whichever symbol/character you are using or add/remove more.

E.g. [[MY_VARIABLE_NAME]] would be matched with [[[A-Za-z0-9_]+]]
