minidom: find what file the element was created in?

P: 1
Hi all,

(Python 2.5 under cygwin)

I'm reading a bunch of XML files and merging them in memory - each file contains a number of packages which are to be merged:

Expand|Select|Wrap|Line Numbers
  1. for fname in gInfiles:
  2.     doc=xml.dom.minidom.parse(fname)
  3.     if gDoc is None:
  4.         gDoc=doc
  5.         gTlp=relPathQuery(gDoc,'TOP-LEVEL-PACKAGES')[0] # There shall be only one
  6.     for nPackage in relPathQuery(doc,'TOP-LEVEL-PACKAGES/PACKAGE'):
  7.         info("  - " + relPathQueryContent(nPackage,'SHORT-NAME','(unknown)').strip())
  8.         if doc!=gDoc:
  9.             gTlp.appendChild(nPackage.cloneNode(1))
There is a lot of validation besides XML validation, which my python does, by querying the tree, and checking that the input makes sense. If it does not make sense, or if I want to emit warnings, I would like to give the user meaningful pointers into the source files. That is, I want

Expand|Select|Wrap|Line Numbers
  1. ERROR: %{problem}s at %{filename}s, line %{lineno}d.
I've crawled around the minidom and DOM python documentation but haven't seen anything that might help. I also started to look in the source of and but it's getting rather time consuming when someone might just know this OTOH!

Anyone done this? Ta
