we have a similar problem and we use the Amara xml Toolkit for python. To avoid
the big memory consumption use pushbind. A 30G bme catalog file takes a maximum
up to 20min to import. It might be faster because we are preparing complex
objects with an orm. So the time consumption depends how complex the catalog is.
If you use amara only to perform a conversion from xml to csv the final import
can be done much faster.

Thanx Lutz, I will try to use that Amara and also I will try to parse it with SAX.
I have tried twig and some other parsers but they consumed too much RAM.
