Can we assume that the only double quotes are those surrounding the
label string?  If so, you can use that to split the input file into
three files, something like:

cat file | cut -f1 -d\" > file1
cat file | cut -f2 -d\" > file2
cat file | cut -f3 -d\" > file3
sed 's/\//_/g' < file2 > file2.new
paste -d\" file1 file2.new file3 > outputfile

I didn't test this, but it might work...
