Question

sample input (orgtext = a[crlf]b[space]c[crlf] )

I like to store each word a,b, c to the words array with the original suffix crlf or space. Currently calling SPLIT drops the suffix as its separator, but I like to store separator as well. Can I adjust regexp to return also suffix and still split?

Words = new Array;  var ar: Array = orgtext.split( /\s+/  );     for (var i:int = 0; i<ar.length;i++ ) { Words.push(  ar[i] +'suffix here' );  }

Generally you would use keep calling exec with an expression that uses the global (g) so that the lastIndex will be set.

var input : String = 'asd asd asd asd'; var output : Array = new Array();  var expr : RegExp = /[^\s]+(?:$|\s+)/g; var result : Object = expr.exec(input);  while(result != null) {     input.push(result[0].toString());     result = expr.exec(input); } 

Depending on the number of matches you can expect, it might be faster to use…

([^\s]+(?:$|\s+))+ 

… which will capture all possible matches in one exec(). The matches will be available in result[1] … result[n]
