Regex Match string AND not match string

Someone help me please!

I need a regular expression that match one string, and not match a second string in one.

example

The searchstring may not match the word "s=001" AND must match the word "msisdn="

I'm stuk on de Regex: ^((?!s=001).)*$

this search-string should return true:
/fotos/site29/set3/518.html?msisdn=%2B31&hash=1FCFA5888E

en this one false:
/fotos/site29/set3/518.html?msisdn=%2B31&hash=1FCFA5888E&s=001

Who can help me??

Hi,

regexes are the wrong approach for this. If I understand you correctly, you want to make sure that certain URL parameters are given and others not.

The server language you're using (whatever that is) is much better suited for this kind of task. The parameters are probably parsed automatically (in PHP, for example, they're in the $_GET array). So you can do some simple checks directly on the parameters and don't need to write your own home-made URL parser.

Thanks for the quick response, but the problem is i have to check it with Regex and it's not an option to script it.
If it really is impossible, i have to find an other solution..
But thanks anyway!

Says who? What exactly do you need this for?

Yes, it's possible with a regex, but that's just ugly and far from a clean solution. And I can hardly think of a context where you actually have to parse and filter URL parameters with a regex.

Anyway, my idea would be

I think i can use this! thanks
