Here's my quick perl solution...

Save as "junk.pl", then run as "junk.pl <file1> <file2> <file3> ... ". 
Each file is renamed to <file>.old, output <file>.  For each

Note, this assumes that there are no double quotes in the label
expression to be manipulated.  I can't see how you'd determine the
end of the expression if this isn't true (unless double quotes
might be quoted with a backslash or something).  

#!/usr/bin/perl

foreach my $outfile (@ARGV) 
{
    my $infile = $outfile . ".old";

    print "infile: $infile\n";
    print "outfile: $outfile\n";

    my $line, $s1, $s2, $s3;

    rename $outfile, $infile;

    open INFILE, "<$infile";
    open OUTFILE, ">$outfile";

    while ($line = <INFILE>) {
        if ($line =~ /^(.*)label=\"([^\"]*)\"(.*)$/)
        {
            $s1 = $1; $s2 = $2; $s3 = $3;
            $s2 =~ s/\//_/g;
            print OUTFILE $s1 . "label=\"" . $s2 . "\"" . $s3 . "\n";
        }
        else
        {
            print OUTFILE $line;
        }
    }

    close INFILE;
    close OUTFILE;
}
