Hi,

I build a small parser to create your perl structure from your file. A part of this is a escape function, that would escape special chars in s///.

The parsing is done specially by the parse.

#!/usr/bin/perl -w

use strict;
use Data::Dumper;

sub escape {
        my $str=shift;
        $str=~s/\\/\\\\/g;
        $str=~s/\[/\\[/g;
        $str=~s/\]/\\]/g;
        $str=~s/\(/\\(/g;
        $str=~s/\)/\\)/g;
        $str=~s/\{/\\{/g;
        $str=~s/\}/\\}/g;
        $str=~s/\^/\\^/g;
        $str=~s/\//\\\//g;
        $str=~s/\+/\\\+/g;
        $str=~s/\-/\\\-/g;
        $str=~s/\$/\\\$/g;
        $str=~s/\&/\\\&/g;
        $str=~s/\*/\\\*/g;
        $str=~s/\|/\\\|/g;
        $str=~s/\?/\\\?/g;
        return $str;
};

sub parseoptions {
        my $options=shift;
        my @opts=();
        $options=~s/\s+$//;
        for my $opt (split /\n/, $options) {
                $opt=~/^\s*(\w+)\s+(.*)$/;
                my $data={name=>$1, content=>$2};
                unshift @opts, $data;
        }
        return \@opts;
}

sub parse {
        my $lookat=shift;
        my @struct=();
        while ($$lookat=~/^\s*(\w+)\s+(\w+)?\s*{/) {
                my $data={type=>$1,name=>$2};
                my $str=escape($&);
                $$lookat=~s/^$str//;
                if ($$lookat=~/^[^}]+{/) {
                        $data->{content}=parse($lookat);
                        $$lookat=~s/^\s*}//;
                } else {
                        ($data->{content})=$$lookat=~/^\s*([^}]+)\s*}/
+;
                        my $str=escape($&);
                        $$lookat=~s/^$str//;
                        if ($data->{type} eq 'single') {
                                $data->{content}=parseoptions($data->{
+content});                        }
                }
                unshift @struct, $data;
        }
        return \@struct;
}

my $quest="";
while (my $line=<>) {
        $line=~s/^\s+/ /g;
        $quest.=$line;
}

my $struct=parse(\$quest);

print Dumper($struct);

Hope this helps.
