Code:

        sub("\",", " ", $startlabel_is_n_word);
        printf "%s",substr($startlabel_is_n_word, 9) #this prints the string starting with '[label="ActualLabel' as 'ActualLabel'.
        labelword=startlabel_is_n_word+1;
        if($labelword~/\"/) {} else {
        do
        {    
            labelword_cleaned = $labelword;
            sub("\",", " ", labelword_cleaned);

            if($labelword~/\"/) { 
            # This bit of code brings us out of here if we encounter an '"'.

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
