HTTP query parameters regular expression

Question

Probably a minor one for the pros...

I want to detect a string of query parameters like:

var1=val1&var2=val2&...

I tried:

((.*)?(#[\w\-]+)?$&*)*

which is fine except it also matches

var1=val1&

which I don't want.

EDIT:

Tried also this:

(.*)=(.*)&*

is it a good solution?

Can you provide some examples of input data and expected results ? — Muldec

Try this:

^([^=]+=[^&]*&)*([^=]+=[^&]*)$

Here, following matches one key-value pair.

[^=]+=[^&]*

So, zero or more key-value pairs each ending with &:

([^=]+=[^&]*&)*

And, one key-value pair at the end with no following &:

([^=]+=[^&]*)

Try the following,

(?:&?[^=&]*=[^=&]*)+

You can test it from here as well as its description.

Tried also this:
(.*)=(.*)&*

No. What about the input string is something like var1=val1&var2=val2&...sdsad3423--**909 ?
