Sailpoint’s IdentityIQ uses xml files for importing various objects like applications, rules. If you have a script that uses a ‘logical and’ (&)  in your code , normally the import fails. This is because of the way in which normal xml files are read. This is one of the special characters.

To solve the problem replace all the ‘logical and’s which are represented by the character ‘&’ to ‘&’. This would make your import successful.
