Parse tokens into several arrays/lists

[abrasat]

I am struggling to find a solution to parse tokens into several different arrays/lists.
The string to tokenize/parse looks like this

(x:x1, x:x2, x:x3, y:y1, z:z1, z:z2)

The result should be stored in a node like this:

class Node
{
  List<string> xItems; // contains all items for token x: (x1, x2, x3 in the example above)
  List<string> yItems; // contains all items for token y: (y1 in the example above)
  List<string> zItems; // contains all items for token z: (z1, z2 in the example above)
}

, or more generically, in a node like this

class MoreGenericNode
{
  Dictionary<string,List<string>> items; //the dictionary key is the token (x:, y:, z:, ...)
}

The defined tokens are x:, y:, z:, as well as the comma and the left/right brackets.
Is it possible to get the result information by parsing the input string only once, or is it necessary to parse the string several times, for each token?
