Line numbers and other information in XML parsing

What is the best method of figuring out data like line or column numbers
while parsing XML?

I use the XM_EIFFEL_PARSER with an implementation of XM_CALLBACKS. The
provided features (callbacks) do not allow to query the current parse
position in the file. I solve the problem by passing the
XM_EIFFEL_PARSER instance to the implementation of XM_CALLBACKS.

Is there a better way of doing this?

It looks like that's how it's done in XM_CALLBACKS_TO_TREE_FILTER.
You have to first call `enable_position_table' to pass the parser.
Then `handle_position' is able to fill in `last_position_table'.
