So your looking from something that starts with '{' and continues
while not a ')' ...
  /{([^}]*?)}/
If you are already using the "?" meta character then you can simply do this:
/{(.*?)}/
The "while not"-approch is useful if you don't want to use the "?" meta 
character (to be compatible to regex engines which don't support this). 
But then it would look like this:

/{([^}]*)}/
But all these expressions are to lazy for the required work. The tags 
should be matched more exactly using this:

/{$([\w\.]+)}/
This implies that the variable names always begin with a dollar 
character and they can contain upper and lowercase characters, numbers, 
underscores and periods. The variable name must contain at least one 
character, so {$} is not matched.
