Dear @nasbench,

I quickly implemented the changes you suggested, the datasets are now xml and I also updated the yml file.

@AAtashGar stop using AI to fix things. As this will lead to closing this PR :)
I fixed the yaml, but you have to push the fix for the logs - Here is an example how they should look like https://media.githubusercontent.com/media/splunk/attack_data/5f19dcf9bc26db70a83fd4ef9e14fedbd3a45535/datasets/attack_techniques/T1036/executables_suspicious_file_path/exec_susp_path2.log

Just do an export raw from Splunk without additional formatting

Dear @nasbench,
The problem with the raw log has been fixed, I hope there will be no more problems
Thanks for your help and guidance
