minidom help -- line number

On Saturday 14 August 2010, it occurred to GZ to exclaim:

The DOM does not contain things like line number information. You work with 
the structure of the document, not the appearance of the file you happen to be 
using as a source. You can't use line numbers with minidom.

For stream-based parsers like SAX and eXpat (both in the standard library) 
this makes more sense, and they both allow you to check the current line 
number in one way or another.
