Lire XML formats aren't designed for the task you are trying to achieve.

The XML formats you are probably talking about is the Lire DLF Schema
Markup Language. These XML files do not describe a "log format" but a
data schema.

New log formats are implemented in Lire by writing a DLF converter which
takes care of parsing the native log format and giving the data
extracted in the correct schema to the framework.

DLF isn't even a real log format, it is more of a convenient
abstraction.
