FINDKEYS
With FINDKEYS you specify filters to extract specific keys from XML variables. The keys are extracted as XML so you could, for example, extract keys from one XML variable and write them to a second XML variable.
Syntax
                           FINDKEYS("String xml definition","Key","Property
                              			 name","value","separator") 
                           		       
Example
This example returns the [Product] key from gv_setproperty:
                           =FINDKEYS(GlobalVariables.gv_setproperty.Text,"[product]","unique",
                              			 "[product].[all tires].[car tires all season]",":") 
                           		       
Example
=FINDKEYS(GlobalVariables.gv_setproperty2.Text,"[product]","unique", "[product].[all tires].[car tires all season]","[region]","unique", "[region].[all regions].[europe]",":")
