.htaccess RewriteRule

[rayzun]

I would like to check an area of my urls for only digits using .htaccess

RewriteRule greens.htm((.*)) /indexx.php

  http://domain.com/greens.htm(14008)

mainly this - (14008)
.. lunch.htm( )

The parenthesis will be used to store a zipcode
4 - 5 digits in length ?

Something like this, perhaps?

RewriteRule greens.htm\(([0-9]{4,5})\) myscript.php?zipcode=$1
