Regular expression to match brackets

Question

For a templating engine, I am using regular expressions to identify content under brackets in a string. For example the regex needs to match {key} or or [element

Answer 1

The best way to do this, especially if different brackets can have different meanings, is to split into 3 regular expressions:

var rx1 = /\[([^\]]+)]/;
var rx2 = /\(([^)]+)\)/;
var rx3 = /{([^}]+)}/;

These will match any text surrounded by [], (), and {} respectively, with the text inside in the first matched group.
