Could you send me some sample log lines that currently aren't being parsed

And how will XML logging make parsing easier?  In my experience, XML makes
files considerably larger, slower to process, and has no increase in
functionality over the old standard methods of formatting logs (and other

XML data files are all gibberish until both sides agree on how the data
items are to be formatted and what each data item means.   Which is the same
sitation with the old methods of data interchange, such as plain ASCII tab
delimited files, except that tab delimited files are much smaller and faster
to process.  There is a possible exception when we are talking complex
documents (Word processing, etc.), but this isn't the case with data logs,
where the content is rigidly defined.  IMO.
