Hi, were you able to do this? If not, here is how it works, just as Krishna said.
You can extract the XML file either with the option Krishna pointed out, or just extract directly to your local Downloads folder.
You need to extract the security group(s) you wish to remove a user from. In my case, if I delete the entire row with "TEST_USER_2", save and load the file into the system, the user is no longer assigned to the security group "MySecurityGroup". With RegEx (Regular Expressions), search and replace in large files is saving you a lot of time.
Of course, you can also use business rules to do this as cbriscoe pointed out as an alternative to doing this in the XML.
