In general this is a good suggestion, but as I understand, the valuable
info is in the _binary_ log file. Once you've decided what you want to
extract from this file, and then extract it with lx and ltrace, the
output format serves only for display and presentation purposes.

Can you elaborate more on "simply displaying collected numbers without
I don't understand what needs special formatting and annotation that
be done by processing the _binary_ log file.

XML log files has a mush stronger added value for analysis, but making
these files so big is a nuisance. I would prefer an independent program
that will convert the _binary_ format to XML which I could use when in
