AWK Script

awk -F '|' '{
  for (i=1; i<=NF;i++){
    split($i, tag_value, "="); #Split field into tag and value
    tag = tag_value[1];
    value = tag_value[2];
    # Here you would use the information from the FIX44.xml (loaded into a data structure in awk) to interpret `tag` and `value`
    if (tag == "8") {
      print "Order ID: " value;
    }
    # ... Similar Processing for other tag ..
  }
}' input_fix_messages.txt

Another code with if condition

awk -F '|' '{
  for (i=1; i<=NF;i++){
    split($i, tag_value, "="); #Split field into tag and value
    tag = tag_value[1];
    value = tag_value[2];
    # Here you would use the information from the FIX44.xml (loaded into a data structure in awk) to interpret `tag` and `value`
    if (tag == 35 && value == 0) {
      print "Heartbeat"
      exit; # Exit after finding the Heartbeat message
    }
    # ... Similar Processing for other tag ..
  }
}' input_fix_messages.txt

Another sample code with switch case

awk -F '|' '{
  for (i=1; i<=NF;i++){
    split($i, tag_value, "="); #Split field into tag and value
    tag = tag_value[1];
    value = tag_value[2];
    # Here you would use the information from the FIX44.xml (loaded into a data structure in awk) to interpret `tag` and `value`
    switch (tag) {
      case 35:
        if (value == 0) print "Heartbeat";
        if (value == 8) print "Execution Report";
        break;
      case 8:
        print "FIX Version: " value;
        break;
      case 49:
        print "Source ID: " value;
        break;
      case 56:
        print "Destination ID: " value;
        break;
      default:
        print "Unknown tag: " tag, value;
    }
    # ... Similar Processing for other tag ..
  }
