From your post what i understood is you need a file which contains filtered content of header and rule for filter is given by a file.
let's say rule file is rule.txt (containing A_1 A_2 etc) and file with header is file.html

Code:
head -1 file.html >temp
 
for $pat `cat rule.txt`
grep -vPw '$pat\.[A-Z]' temp >temp1
cat temp1 >temp
done

Path::Dispatcher::Match(3pm)				User Contributed Perl Documentation			      Path::Dispatcher::Match(3pm)

NAME
Path::Dispatcher::Match - the result of a successful rule match SYNOPSIS
my $rule = Path::Dispatcher::Rule::Tokens->new( tokens => [ 'attack', qr/^w+$/ ], block => sub { my $match = shift; attack($match->pos(2)) }, ); my $match = $rule->match("attack dragon"); # introspection $match->path # "attack dragon" $match->leftover # empty string (populated with prefix rules) $match->rule # $rule $match->positional_captures # ["attack", "dragon"] (decided by the rule) $match->pos(1) # "attack" $match->pos(2) # "dragon" $match->run # attack("dragon") DESCRIPTION
If a Path::Dispatcher::Rule successfully matches a path, it creates one or more "Path::Dispatcher::Match" objects. ATTRIBUTES
rule The Path::Dispatcher::Rule that created this match. path The path that the rule matched. leftover The rest of the path. This is populated when the rule matches a prefix of the path. positional_captures Any positional captures generated by the rule. For example, Path::Dispatcher::Rule::Regex populates this with the capture variables. named_captures Any named captures generated by the rule. For example, Path::Dispatcher::Rule::Regex populates this with named captures. parent The parent match object, if applicable (which may be set if this match is the child of, for exampl, a Path::Dispatcher::Rule::Under prefix) METHODS
run Executes the rule's codeblock with the same arguments. pos($i) Returns the $ith positional capture, 1-indexed. perl v5.12.4 2011-08-30 Path::Dispatcher::Match(3pm)
