How to log QuickFix message in human-readable format

Question

I want to log QuickFix messages in sort of parsed mode like tagname,Value

I cannot find existing functionality. I am using QuickFix.Net.

I was thinking about providing some sort of method that would iterate through all presenting tags and parse them using data dictionary.

There is a Java sample http://www.quickfixj.org/confluence/display/qfj/Using+Message+Metadata that can be converted to .NET and that may prove to be useful:

public class MetadataExample {
    public static void main(String[] args) throws Exception {
        DataDictionary dd = new DataDictionary("FIX44.xml");

        Message m = new Message("8=FIX.4.4\0019=247\00135=s\00134=5\001"
                + "49=sender\00152=20060319-09:08:20.881\001"
                + "56=target\00122=8\00140=2\00144=9\00148=ABC\00155=ABC\001"
                + "60=20060319-09:08:19\001548=184214\001549=2\001"
                + "550=0\001552=2\00154=1\001453=2\001448=8\001447=D\001"
                + "452=4\001448=AAA35777\001447=D\001452=3\00138=9\00154=2\001"
                + "453=2\001448=8\001447=D\001452=4\001448=aaa\001447=D\001"
                + "452=3\00138=9\00110=056\001", dd);

        MessagePrinter printer = new MessagePrinter();
        printer.print(System.out, dd, m);
    }
}

public class MessagePrinter {

    public void print(DataDictionary dd, Message message) throws FieldNotFound {
        String msgType = message.getHeader().getString(MsgType.FIELD);
        printFieldMap("", dd, msgType, message.getHeader());
        printFieldMap("", dd, msgType, message);
        printFieldMap("", dd, msgType, message.getTrailer());
    }

    private void printFieldMap(String prefix, DataDictionary dd, String msgType, FieldMap fieldMap)
            throws FieldNotFound {

        Iterator fieldIterator = fieldMap.iterator();
        while (fieldIterator.hasNext()) {
            Field field = (Field) fieldIterator.next();
            if (!isGroupCountField(dd, field)) {
                String value = fieldMap.getString(field.getTag());
                if (dd.hasFieldValue(field.getTag())) {
                    value = dd.getValueName(field.getTag(), fieldMap.getString(field.getTag())) + " (" + value + ")";
                }
                System.out.println(prefix + dd.getFieldName(field.getTag()) + ": " + value);
            }
        }

        Iterator groupsKeys = fieldMap.groupKeyIterator();
        while (groupsKeys.hasNext()) {
            int groupCountTag = ((Integer) groupsKeys.next()).intValue();
            System.out.println(prefix + dd.getFieldName(groupCountTag) + ": count = "
                    + fieldMap.getInt(groupCountTag));
            Group g = new Group(groupCountTag, 0);
            int i = 1;
            while (fieldMap.hasGroup(i, groupCountTag)) {
                if (i > 1) {
                    System.out.println(prefix + "  ----");
                }
                fieldMap.getGroup(i, g);
                printFieldMap(prefix + "  ", dd, msgType, g);
                i++;
            }
        }
    }

    private boolean isGroupCountField(DataDictionary dd, Field field) {
        return dd.getFieldTypeEnum(field.getTag()) == FieldType.NumInGroup;
    }

}
