help on mod_rewrite

[Westcoast Sheri]

Hello. How do I do this:

If a visitor types in any number after my url, I want mod_rewrite to
convert it to my url/anotherpage.htm l?number=number _visitor_typed

Example:

http://www.mysite.com/12345678.html

would result in:

http://www.mysite.com/anotherpage.html?number=12345678

another example:

http://www.mysite.com/000111000.html

would result in:

http://www.mysite.com/anotherpage.html?number=000111000

Thank you.
