How to parse Microsoft-Windows-TaskScheduler/Operational logs?

Can someone help me out with a regular expression to parse Microsoft-Windows-TaskScheduler/Operational logs? I don't think I am the first to want to extract fields from this log? I am pulling in the above logs. I tried renderxml=true and renderxml=false.

I ran into this error below when trying to extract manually and the solution is to use my own regular expression.
The extraction failed. If you are extracting multiple fields, try removing one or more fields. Start with extractions that are embedded within longer text strings.

An example of the line I am trying to extract values is:

Message=Task Scheduler started "{CD0B4355-0A74-4D11-A816-04E3C5B138C5}" instance of the "\Adobe Flash Player Updater" task for user "contso\system301$"

I want to extract "\Adobe Flash Player Updater" as TaskName and "contso\system301$" as TaskUser.

Any help is appreciated.
