GETPROPERTIES
This function returns a list of the properties of a specified key from an xml variable. The function returns a string. It is similar to GETPROPERTIESA.
           You can use the asterisk (*) character at the beginning or end of a string as a wildcard. For example, to return particular keys or properties. Asterisks within a string do not act as wildcards. A wildcard search returns only the first matched key or property. 
           
         
            Note: We cannot guarantee the order in which keys or properties are matched.
           
          Syntax
GETPROPERTIES("XML_properties","key","separator")
         Example
=GETPROPERTIES(ReportVariables.rv_xmlvariable.text,"[Product]",",")
           
            Note: In GETPROPERTIES, the 
          .text attribute is optional. In GETPROPERTIESA, the .text attribute is required.
           GETPROPERTIES is a list function. It can be used in server lists, relational lists, and in slices.
