Subject: Replacing based on regular ecpressions

Hi,

I'm writing a ruby script that does a batch search-and-replace command.

In each line of the file that is opened, I would like to delete part
of the entire part matched by a regrex. For example,


line.gsub(/(Tennis\/Soccer\/.+?).+?){
 puts $& # entire match
 puts $1 # the first match

}

I can successfuly identify the parts I need in the regres, now I want
to only keep the first match. Something like "$&" - "$1".


I tried different methods such as String#delete, but they didn't work for me.
