in reply to Can't quite get this regex working

You could either use  /\Q[[$tag_name]]\E((.|\n)*?)\[/) or add a modifier to the regex so that '.' matches '\n' as well, I think it was m or s

    Generally where you are matching up to some expected character a negated character set is better than .*?. In this case ([^\[]*) would be appropriate.

      Careful, when the delimiters are doubled, the file format might allow a single ] or [ on the inside, in which case the negated char class doesn't work.

      In that case you can use 

      (?s:(?!\]\]).)*

        I much prefer: 
        /[^]]*(?:][^]]+)*/

        which doesn't require any lookahead, backtracking or modifiers.
