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

audit_add_rule_data

AUDIT_ADD_RULE_DATA(3)						  Linux Audit API					    AUDIT_ADD_RULE_DATA(3)

NAME

       audit_add_rule_data - Add new audit rule

SYNOPSIS

       #include <libaudit.h>

       int audit_add_rule_data (int fd, struct audit_rule_data *rule, int flags, int action);

DESCRIPTION

       audit_add_rule adds an audit rule previously constructed with audit_rule_fieldpair_data(3) to one of several kernel event filters. The fil-
       ter is specified by the flags argument. Possible values for flags are:

       o  AUDIT_FILTER_USER - Apply rule to userspace generated messages.

       o  AUDIT_FILTER_TASK - Apply rule at task creation (not syscall).

       o  AUDIT_FILTER_EXIT - Apply rule at syscall exit.

       o  AUDIT_FILTER_TYPE - Apply rule at audit_log_start.

       The rule's action has two possible values:

       o  AUDIT_NEVER - Do not build context if rule matches.

       o  AUDIT_ALWAYS - Generate audit record if rule matches.

RETURN VALUE

       The return value is <= 0 on error, otherwise it is the netlink sequence id number. This function can  have  any	error  that  sendto  would
       encounter.

SEE ALSO

       audit_rule_fieldpair_data(3), audit_delete_rule_data(3), auditctl(8).
