unrealscript - Regex to capture key-value comma-separated values -

i'm trying write regular expression parse values out of unrealscript serialized objects. part of involves lines this:

(x=32.69,y='123.321',z="a string commas, complicate things!",w=class'some.class') 

the resultant capture should be:

[     {         'x':32.69,         'y':'a string commas, complicate things!',         'z':'class\'some.class\'     } ] 

what want able distinguish between key (eg. x) , value (eg. class\'some.class\').

here pattern i've tried far, capture simple set of values (currently doesn't try handle commas inside values, now):

pattern

\(((\s?)=(.+),?)+\) 

data set

(x=32,y=3253,z=12.21) 

result

i'm still novice these regular expressions , appreciated!

thanks in advance.

you can try regex associate key , value pairs:

(?!^\()([^=,]+)=([^\0]+?)(?=,[^,]+=|\)$) 

regex live here.

explaining:

(?!^\()         # not match initial '(' character  ([^=,]+)        # match key .. take last comma =               # till next '=' character  ([^\0]+?)       # combination '[^\0]' - key's value                   # @ least 1 digit '+'                   # stops in first occurrence '?'  (?=             # occurrence?      ,[^,]+=     # comma ',' , key '[^,]+='                   # important: without key:                   # occurrence stop in first comma                   # should or should not delimiter-comma       |\)$        # or '|':  value can last 1                   # has not key in sequence,                   # so, must accept value                   # ends '$' in ')' character  )               # 

hope helps.
