How to create a reg exp to parse such url?

So we have http://127.0.0.1:4773/robot10382.flv?action=read we need to get out from it protocol, ip/adress, port, actual url (robot10382.flv here) and actions (action=read here) how to parse all that into string vars in one reg exp?

Sometimes when passing a file path to a SWF you would like to perform FileExistance check before passing the file to an AS3 class. To do so you want to know if a URI is a file or an http URL or any other URI with specific protocol (moniker). The following code will tell you if you are dealing with a local full or relative path.

/(\w+)\:\/\/(\d+\.\d+\.\d+\.\d+)\:(\d+)\/(\w+)\?(.+)/ : $1 - protocol, $2 - ip, $3 - port, $4 - actual url, $5 - actions

there's also another way:
protocol : url.split('://')[0]
ip/domain name : url.split('://')[1].split(':')[0] (or if no port specified - url.split('://')[1].split('/)[0]
port : url.split('://')[1].split(':')[1].split('/')[0]
actual url : url.split('?')[0].split('/').reverse()[0]
actions : url.split('?')[1].split('&')/*the most possible separator imho*/ elements of this array can also be spliced('=') to separate variable names and values.
i know there's an opinion that splice shouldn't be used, but i think it's just beautiful when used properly.

I'm surprised that AS3 does not include proper URL parsing facilities. To put it simply, it is not easy to safely parse a URL using an RE. Here's an example of doing it though.
