Regex: (?si:<option value=\\\"(?<year>.*?)\\) shouldn't this be the right way to get the year?. meaning for year group, get all characters as long as you don't hit \

try

\<option\svalue\=\\\"(\d*)\\\"

This is the plain regex. change it to what language you are using it

It depends exactly what language you're using, but try <option\s+value=(\\\")?(\d+)(\\\")?>.

Here's it working in Python:

>>> re.findall("<option\s+value=(\\\")?(\d+)(\\\")?>", text)
['1999', '2000', '2001', '2002', '2003', '2004', '2005', '2006', '2007', '2008', '2009']
