Multiple trim operation in preprocessing

[V.N.]

Hi!
I have an item which gets an event from windows server eventlog. Each event has valuable info and ending which I don't need absolutely.
For example,

CryptoStorage state has switched to mounted

For more information, see Help and Support Center at
http://www.site.com/support

I tried to trim all this trash with preproccessing but I could trim only last string "http://www.site.com/support".
How to trim the previous one I can not understand. Maybe it possible to use regular expressions to solve the problem but I wasn't successful in that activity.
Any help appreciated.

Hi, V.N.
Try Regular expression like this one:
pattern: ^([\s\S]*)For\smore\sinformation
output: \1

Thanks a lot!
It works!
