问题
npinti helped me create a regex to remove the querystring and match the remaining segments from the url /seattle/restaurant/sushi?page=2: "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 have tried modifying the above to do the same trick on the url /seattle/restaurant?page=2 but I could not get it right. I don't know if there will be af querystring or not or the parameters of the querystring. So I need the flexibility from the regex above which will match and discard the ? and everything which follows.

Your rewriterules may look like:
RewriteRule /([^/]+)/restaurant/([^/]+)$ mynewpage.php?group1=$1&group2=$2 [QSA,NC,L]
Your may search for what QSA, NC, and L mean thanks to the links I provide below.
I'm sorry but your question sound very like "I'm not very good, so can someone do the job for me?". I mean, just look around, you'll get a lot of answer, just get your hands dirty.
- Here's the wiki of serverfault.com
- The howto's htaccess official guide
- The official mod_rewrite guide
And if that's not enough:
Two hints:
If you're not in a hosted environment (= if it's your own server and you can modify the virtual hosts, not only the .htaccess files), try to use the RewriteLog directive: it helps you to track down such problems:
# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On
My favorite tool to check for regexp:
http://www.quanetic.com/Regex (don't forget to choose ereg(POSIX) instead of preg(PCRE)!)
回答2:
This should allow you to match all text prior to the ? and nothing else. It will match everything if no ? is present:
[^?]*
Is that all you need to do? Because /(.*?)/(restaurant)/([^?]+).*. looks like it's designed to do something significantly more complicated.
