search txt content and send mail with result

Hi guys,

I'm looking for a script that read a txt file, if it find result different from 0 warnings and 0 errors send a e-mail result with warning number, error number and date.

[4/12/2013 3:00:51 AM] Finished with 0 warnings. (final line)
[4/12/2013 3:00:51 AM] Finished with 0 errors. (final line)

the problem is, the name file changes all day and on this case the script must be look for file based on last modified date.

 file name: 1_1_16f94c73-f73c-427c-8ab9-d319665fad15_635011662668970000_62272
