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.

mlm

FBB::mlm(3bobcat)					      OFoldStream manipulator						 FBB::mlm(3bobcat)

NAME

       FBB::mlm - Manipulator modifying left margins of OFoldStream objects

SYNOPSIS

       #include <bobcat/ofoldstream> or
       #include <bobcat/ofoldstreambuf>
       Linking option: -lbobcat

DESCRIPTION

       The  mlm  class	implements  a  manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
       amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the  request
       then left margin 0 will silently be used.

       Depending  on  the  tab-setting	of  the  OFoldStream  the  inserted value represents the number of blank space characters or the number of
       tab-characters that will be added to the left margin.

       The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream.  If  a
       line  is  still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
       the next word inserted into that line (cf., the example section below)

       A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.

	       out << "hello world (left margin is 0)" << mlm(4) << "
"
		      "this uses a 4 character wide left margin
" <<
		       mlm(-10) << flush <<
		       "left margin -6 changed to 0, active on this line
";
	       return 0;
