OS and browser extraction from useragent

Hi,

I need to extract OS and browser details from useragent. Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) I need to capture Web Browser Version and Operating System Version from each user per visit. Is there any easy way that I can get the info instead of writing python script?
