Assuming that I understand correctly what you're trying to do (i.e., delete the directory portion of the pathname in the first double quoted string on the 4th line of a file), this seems to be an easy way to do it:
Code:
sed  -i '4s/"[^"]*\\/"/' "$FILE"

This will not, however, work correctly if there is no directory given in that first double quoted string.

ppi::token::quote::double

PPI::Token::Quote::Double(3)				User Contributed Perl Documentation			      PPI::Token::Quote::Double(3)

NAME

       PPI::Token::Quote::Double - A standard "double quote" token

INHERITANCE

	 PPI::Token::Quote::Double
	 isa PPI::Token::Quote
	     isa PPI::Token
		 isa PPI::Element

DESCRIPTION

       A "PPI::Token::Quote::Double" object represents a double-quoted interpolating string.

       The string is treated as a single entity, PPI will not try to understand what is in the string during the parsing process.

METHODS

       There are several methods available for "PPI::Token::Quote::Double", beyond those provided by the parent PPI::Token::Quote, PPI::Token and
       PPI::Element classes.

       Got any ideas for methods? Submit a report to rt.cpan.org!

   interpolations
       The interpolations method checks to see if the double quote actually contains any interpolated variables.

       Returns true if the string contains interpolations, or false if not.

   simplify
       For various reasons, some people find themselves compelled to have their code in the simplest form possible.

       The "simply" method will turn a simple double-quoted string into the equivalent single-quoted string.

       If the double can be simplified, it will be modified in place and returned as a convenience, or returns false if the string cannot be
       simplified.
