Extract date from archived Windows Event Viewer files using zcat or zgrep

We have daily log files of Windows server that are zipped every week. The events are in XML format. I need to run a query on these log files and extract a particular date from each event that gets a hit. I'm able to find every file that contains a particular string, but that isn't what I'm looking for. Take the event below for which there are two problems: 1) I need to find EventID == 5061 && SID == S-1-12-1-1032717433-1282942920-404204970-2072513611 in one event. This is problematic because I don't know how to distinguish different events; however, all new events start with "Event xmlns". I've tried to figure out an approach to search text between two "Event xmlns" strings, but I've not had any luck. 2) The query needs to return the SystemTime, which in this case is "2019-10-18T18:59:34.538976500Z". I'm sure this is possible, but I've not made headway. Does anyone have an idea of what I might try? Thanks

Can you please explain how this is Linux related?
I'm trying to use zcat or zgrep on Linux to obtain the data. The archives are stored on a Linux system. It just happens the source of the data is from Windows.
