Thanks for the ideas,
I see I still don't have the hang of this context thing! I still haven't
provided enough
context. So here goes again, to show the entire chain. This might change the
discussion to be about design practice but it will give overview of how I'm
using
the class in question.

Note that ElementTree provides both a SAX-like interface (look for the
'target' property of parsers) and an incremental parser (iterparse).
Interesting, I didn't realise that.
I've only ever used it to build a tree.
XML parsers fall into 2 groups. Those that parse the

This list provides defines 2 tables that need to be paired and then
compared.
So two instances of a TestTable object maybe?
reference_table_name
reference_dburi
reference_rows
test_table_name
test_dburi
test_rows
keys
Looks like two TestTable objects and a set of

Yes. self.date is set in the constructor.

This reply is also to Alan's suggestion to provide more context.
The situation concerns databases, where in one schema table I've got a
'compare list'.
This list provides defines 2 tables that need to be paired and then
compared. Before
any comparing happens I 'filter' the compare list doing sever

I have the following idea for multiplexing logfiles (ultimately into heapq):
import gzip
class LogFile:
def __init__(self, filename, date):
self.logfile = gzip.open(filename, 'r')
for logline in self.logfile:
self.line = logline
self.stamp = self.timest
