Regular Expression to take parts of a URI

Hi.

I'm tryingo to build a regular expression that takes part of a URI that could vary in function of where the customer is, for instance:

http://xxxxxxx.com/products

I'd like to get products.

http://xxxxxxx.com/products/furnitures

I'd like to get products/funitures

http://xxxxxxx.com/products/furnitures/tables.

I'd like to get products/furnitures/tables but nothing beyond this, I mean if I've

http://xxxxxxx.com/products/furnitures/tables/night_table.html

I'd like to get /products/furnitures/tables

But I don't know how to get it... I've build one, but get all the stuff from /product... including all the parts of the URI

And since the application has several thousands of products, I'm getting a lot of values that i don't want. Anyone knows how to build it?

Thanks in advance and best regards

sorry... I've explained it wrong... what i need to exclude is more than third category, the final part of the URI is excluded with the regex that I've build... I mean:

http://xxxxxxx.com/products/furnitures/tables/night_tables/special/night_table.html

I'd like to get /products/furnitures/tables and nothing else.

Thanks in advance and best regards

does the following work?

(/[^/]/[^/]/[^/]*)

Oh wait, I re-read your original post. here's the edited version:

(/[^/]+/?[^/]+/?[^/]+)

Edit: the limitation here is that the first URI part needs to be at least <regex> /... </regex> in order to match. If you also need to match the case where the URI is simply "/" then the following should be used:

(\A/\Z\|/[^/]+/?[^/]+/?[^/]+)

This one doesn't work for:

www.test.com/product/details.html

www.test.com/product/cat2/details.html

I think it should be:

com/([^/]+/?[^/]+/?[^/]+)/

Just so he doesn't get the host part and also excludes any last element that does not end with "/" such as .html, etc

Just be mindful that the request

www.test.com/product

Won't match because there is no "/" at the end, not sure if we can have the best of both worlds, getting requests that don't end with a "/" and also not capturing the part of the request that ends with ".*"

the host isn't considered in the URI Part BT Measure.

Does the /product/details.html exist? That seems like it wouldn't...
