This is great for smaller files, but i have 40 reports that push through to a 1Gb .nessus file. it takes a good 5Gb of RAM to run this. if anyone knows of a script that uses iterparse (or similar), it would be great to see.

This works perfect. I merged 56 reports with more than 25,000 hosts.

Great,useful~
