python - Parsing Very Large XML Files Using Multiprocessing

Question

I have a huge XML file, and I'm a tad bit at a loss on how to handle it. It's 60 GBs, and I need to read it.

I was thinking if there a way to use multiprocessing module to read the python file?

Does anyone have any samples of doing this that they could point me to?

Thank you

For a file of that size, I suggest you use a streaming XML parser. In Python, this would be the iterparse method from cElementTree or lxml.etree:
