regex - Regular Expression to Modify Title on Autoblogged Plugin -

i need rid of words every feed title. example: titles:

vans model 10 . 390 random data nike model 982 . errant default data timberland old school whatever

now, need remove after "from"

the result should be:

vans model 10 . 390 nike model 982 . errant timberland old school

i cannot use search/replace fields because same data present in %content%, solutions custom fields title regex dont know how.

if cannot use search/replace, can use regex lookahead capture content want this:

(.+?)(?=\sfrom)

however, in case use search/replace use regex:

from.*
