Complex regex to split up a string

Question

I need some help with a regex conundrum pls. I\'m still getting to grips with it all - clearly not an expert!

Eg. Say I have a complex string like so:

{s         


        

Answer 1

Find all occurrences of "string in braces" or "just string", then iterate through found substrings and split when a pipe is encountered.

str = "{something:here}{examp.le:!/?foo|bar}BLAH|{something/else:here}:{and:here\\}(.)}"

var m = str.match(/{.+?}|[^{}]+/g)
var r = [[]];
var n = 0;
for(var i = 0; i < m.length; i++) {
   var s = m[i];
   if(s.charAt(0) == "{" || s.indexOf("|") < 0)
       r[n].push(s);
   else {
      s = s.split("|");
      if(s[0].length) r[n].push(s[0]);
      r[++n] = [];
      if(s[1].length) r[n].push(s[1]);
   }
}

this expr will be probably better to handle escaped braces

  var m = str.match(/{?(\\.|[^{}])+}?/g
