Thorbjoern Ravn Andersen commented on LBCLASSIC-22:
---------------------------------------------------
I am neither "pissed" nor "peeved", but I was quite astonished. I have found
it to be due to the difference in our coding cultures and my subconcious
expectations.
So be it.
There are two key functionalities:
1) "generates humanly readable output" - the output is in a form that is
readable to the human eye when browsing the text file containing the output
from the XMLLayout. This _INCLUDES_ the time attribute which contains a
humanly readable version of the timestamp, put in a location where it is useful
in the situation where the human needs to read the logfile. I took great care
in putting the linefeeds in the right places while maintaining DTD conformancy.
2) Uses numeric XML entities instead of CDATA. In my experience this is more
robust to data transports where the encoding is broken - which we have more
often than I like to think about here - as it keeps to 7-bit ascii, AND it is
better to the human reader as "<", ">" and "&" are only found in their proper
form in tagnames and entities and not as a CDATA stream. Also linefeeds etc
are encoded as their numeric XML entity, resultning in each log event
generating exactly two lines of output (but can be very wide).
The goal I am pursuing is to move from processed logs in flat text files (oh
the joy of multi line log messages) into easily reprocessable log files in our
production scenario. Hence a XMLLayout class which generates humanly readable
output while being log4j DTD conformant so it can be processed with e.g.
Chainsaw and hopefully soon Lilith.
I understand your desire to be 100% compatible with log4j. I hope you
understand my need for a different version which is compatible with the log4j
DTD but does not generates 100% identical output. In XML there are many ways
to say the same thing.
