if already know the maximum and sequence of headers, should below easy perl script help you some.

If not, may need extra efforts to make out the header hash first and then use below perl script.


Code:
my %headers=(H1=>1,H2=>2,H3=>3,H4=>4,H5=>5,H6=>6);
my @header_arr = sort {$headers{$a}<=>$headers{$b}} keys %headers;
print join "|", @header_arr;
print "\n";
my %missed;
my $max=$#header_arr;
while(<DATA>){
	chomp;
	my @tmp=split("[|]",$_);
	my %hash=%headers;
	if($.==1){
		map {delete $hash{$_}} @tmp;
		map {$tt{$_}=1} values %hash;
		next;
	}
	else{
		for(my $i=1;$i<=$max+1;$i++){
			if(exists $tt{$i}){
				print "NA|";
			}
			else{
				my $tmp=shift @tmp;
				print $tmp,"|";
			}
		}
	}
	print "\n";
}
__DATA__
H1|H3|H6
12|31|33
23|41|43

curlopt_proxyheader

CURLOPT_PROXYHEADER(3)					     curl_easy_setopt options					    CURLOPT_PROXYHEADER(3)

NAME

       CURLOPT_PROXYHEADER - custom HTTP headers to pass to proxy

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYHEADER,
				 struct curl_slist *headers);

DESCRIPTION

       Pass  a	pointer to a linked list of HTTP headers to pass in your HTTP request sent to a proxy. The rules for this list is identical to the
       CURLOPT_HTTPHEADER(3) option's.

       The headers set with this option is only ever used in requests sent to a proxy - when there's also a request sent to a host.

       The first line in a request (containing the method, usually a GET or POST) is NOT a header and cannot be replaced using this  option.  Only
       the  lines  following the request-line are headers. Adding this method line in this list of headers will only cause your request to send an
       invalid header.

       Pass a NULL to this to reset back to no custom headers.

DEFAULT

       NULL

PROTOCOLS

       HTTP

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.37.0

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
