ePath Notation Example

The following sample illustrates an object structure containing a system object from Site A with a local ID of 111. The object contains a first name, last name, and three addresses. Following the sample, there are several ePath examples that refer to various elements of this object structure along with a description of the data in the sample object structure referred by each ePath.

Enterprise
   SystemObject - A 111
      Person
         FirstName
         LastName
         -Address
            AddressType = Home
            Street = 800 Royal Oaks Dr.
            City = Monrovia
            State = CA
            PostalCode = 91016
         -Address
            AddressType = Office
            Street = 181 2nd Ave..
            City = Monrovia
            State = CA
            PostalCode = 91016
         -Address
            AddressType = Billing
            Street = 100 Grand Avenue
            City = El Segundo
            State = CA
            PostalCode = 90245

• Person.Address.City – Equivalent to Person.Address[0].City.

• Person.FirstName – Uses Person as the context, and is equivalent to Enterprise.SystemObject[@SystemCode=A, @Lid= 111].Person.FirstName with Enterprise as the context.

• Person.Address[@AddressType=Home].City – Returns a single ObjectField reference to “Monrovia” (the City field of the home address).

• Person.Address[City=Monrovia,State=CA].Street – Returns a list of ObjectField references: “800 Royal Oaks Dr.”, “181 2nd Ave.” (the street fields for both addresses where the city is Monrovia and the state is CA). Note that a reference to the Billing address is not returned.

• Person.Address[*].Street – Returns a list of ObjectField references: “800 Royal Oaks Dr.”, “181 2nd Ave..”, “100 Grand Avenue”. Note that all references to Street are returned.

• Person.Address[2].* – Addresses the second address object as an ObjectNode instead of an ObjectField.
