Subject: search reg-exp for exact match

Hi,

I have a regular expression
/\b2003|\2004|\2005|\2006|\2007|\2008|\2009\b/
and i want to check if various years are present.

"2003" =~  /\b2003|\2004|\2005|\2006|\2007|\2008|\2009\b/
returns 0 as expected

"2010" =~  /\b2003|\2004|\2005|\2006|\2007|\2008|\2009\b/
returns nil as expected

But i want only exact matches so when i search for "2003 - 2008" i want
nil returned as there is no exact match for that particular string.  I
thought the \b would give me this but it doesnt.

"2003 - 2008" =~  /\b2003|\2004|\2005|\2006|\2007|\2008|\2009\b/
returns 0 i want nil returned.

Anyone help?

Jb
