[Twisted-Python] parsing url query parameters and values

[Vasil Vangelovski]

Is there any method in the Twisted or Twisted web api I can use to
parse url query parameters and values. This isn't a very naive
algorithm since there are more complicated query strings that can be
constructed, for example:
http://www.example.com/path?param1=val1&param2=val2&&param3=val3
http://www.example.com/path?param1=val1&param2=val2&som=|=val&param3=val3
Ideally I could use something that bulds a dictionary of parameters and values
