Hello Kevin
No, you are not able to import test cases that are in word doc and xml format. The correct format used to import test cases to QAcomplete tool will be Excel / csv file.
Please learn more by clicking on the user guide link listed below:

On the other hand, you can use the 'Fast Edit' option under the Test Management tab to delete multiple test cases that you no longer want. Please remember when you delete this items they will be permanently deleted and you will not be able to retrieve them again. So during this process please make sure you select the correct test cases you want to delete. The following video will show you how to use the 'Fast Edit' option to delete multiple test cases at one time.

Thanks,
