Regex to get uri stem (path) from uri with optional end character

Question

This should be simple but I can't seem to get it exactly right. I need to extract the uri stem/path only from a uri where it could end with a '/' or not and have a query string or not.

So use cases are as follows

• /shopping/cart ----> /shopping/cart
• /shopping/cart/ ----> /shopping/cart
• /shopping/cart/?param1=val1&param2=val2 ----> /shopping/cart
• /shopping/cart?param1=val1&param2=val2 ----> /shopping/cart

So far I have tried ^(\\/.\\*)\\/ and ^(\\/.\\*)\\/?. I also would prefer to stay away from double groupings if at all possible
