.nessus reports merger AKA How to merge multiple Nessus reports (in .nessus file format)

I came across a situation when I had to merge several Nessus reports in a file, for the ease of vulnerability compilation and reporting. Turns out, it was just a google ('s/duckduckgo/google/g') search away.[0] :-)

Here-

1. Keep the python script[1] along with .nessus files in the same directory.
2. Run python script and a folder/file will be created nss_report/report.nessus.

Big thanks to mastahyeti for taking pain to create this wonderful script.

 ..............Done!!!
