Apache Rewrite - help required.

Guys

Im trying to write a pretty URL creator for an online store that Im working on. The idea would be that the URL would look like

http://shop.com/products/widget/red/1234-XYZ 

Where 1234-XYZ is the product code, and this would rewrite to products.php?param1=1234&param2=XYZ. I understand the pseudo code involved would be something like

* Get the request URI
* Write a RewriteCond statement to parse out the 2 parameters into backreferences
* Take the values of the backreference and add RewriteRule like products.php?param1=$1&param2=$2

Its the regular expression Im struggling with. How do I find out if the URI ends with a string in that format, ie. 4 numeric, a hyphen and 3 alphanumeric.

Also, the directory structure could be anything:

/products/1234-XYZ
/products/widgets/1234-XYZ
/products/manufacturer/widget/1234-XYZ
etc

Any ideas?

Look at a cheatsheet: http://www.addedbytes.com/download/regular-expressions-cheat-sheet-v2/png
You can test your regex with an online tool, RegExr.

This might work:

RewriteEngine on  
RewriteRule ^/products/.*(\d{4})-(\w{3})$ /products.php?param1=$1&param2=$2 [L]
