I have the below regex, but how can I remove the querystring entirely if it is present:

^~/(.*)/restaurant/(.*)

eg. the url 

/seattle/restaurant/sushi?page=2

or 

/seattle/restaurant/sushi?somethingelse=something

or 

/seatthe/restaurant/sushi

should just return seattle and restaurant and sushi and remove any querystring if it is present.

(sorry for reposting a similar question, but I couldn't get the answer to work in my previous question).

thanks

This regex:

(/[^?]+).*

Should match the initial section of your URL and put it in a group.

So it will match /seattle/restaurant/sushi and put the value in a group.

You can use something like this: (/.*?/restaurant[^?]+).* if you want to handle just URLs with the word restaurant as the second word between the slashes.

Edit: Something like so should yield 3 groups: /(.*?)/(restaurant)/([^?]+).*. Group 1 being seatthe, group 2 being restaurant and group 3 being sushi. If after the last / there is a ?, the regex discards the ? and everything which follows.

I would like to match "seattle" and "sushi" as separate matches. Also if "sushi" is proceeded by a querystring. In which case I would like to match "sushi" and remove the ? and everything after that. Thanks
Excellent. That works! I tried removing the slash between the last two groups (restaurant) and ([^?]+).* because I would like it to match /seattle/restaurant?page=2 in the same way as /seattle/restaurant/sushi?page=2. But I couldn't get it to work. Since I have a lot of other URLs on the 2. level position like /seattle/restaurant-michelangelo, which should NOT be caught, I guess I need to hardcode the values on the 2. level which SHOULD be caught (eg. restaurant, cafe, take-away). At the third level (/seattle/restaurant/sushi) I don't have the problem, so your suggestion works here. Thanks
How do I modify the regex to match seattle and restaurant from the url /seattle/restaurant? Page =2 and discard the querystring ? I tried modifying the above but could not get it to work. Thanks
@ThomasD: I recommend you open a new question.
thanks. I opened a new question at stackoverflow.com/questions/9145069/need-help-modifying-regex. Thank you for your help. I really appreciate it

You should change your final /./ to match "anything but a question mark" like this

^~/(.*)/restaurant/([^?]*)

Just tried it, and it partially works :-) I would still like it to return "sushi" even though "sushi" might be followed by a querystring. So eg a query like /seattle/restaurant/sushi?page=2 would match "seattle" and "sushi". Right now it seems it doesn't match "sushi" if it is proceeded by a querystring. Thanks
