Yes! you can use the xmlParse() method to perform any administrative tasks that you can perform using arsxml. The 'xml' parameter allows you to specify the xml you want to process - this is the same xml that would be contained in the input file that is passed to arsxml (-i) only it is passed as a String object rather than in a file, the continueOnError parameter is the same as the 'error handling' flag that is passed to arsxml (-e), and the action parameter allows you to specify which type of action (add, update, delete, export, validate). Check the ODConstants for the action constants - for example OD_ARSXML_ACTION_ADD.
