regex - Can't find the right regexp -

I am working with QString (Qt 4.8) and I type this string like src = "http I want to remove: // media.cineblog.it/9/91f/Big-Bad-Wolves-primo-trailer-per-il-crime-thriller-israeliano.jpg " using QRegExp from QString but me Regular expression can not be found to do this The string is not in an IMG tag.

Try using the pattern

  (src = " [^ "] +")
