XPath Tokens

The following tokens are used in XPath queries:

Token Definition
// A Xpath query always starts with the tokens //. These slashes are followed by the designation of the object that is being queried. For example: if you wish to retrieve all Customers the query would resemble the following: //Customers
. The dot is used to separate module names from entity names. E.g. if you wish to retrieve all the customers (objects) in the sales module you would start the query with: //Sales.Customer
/ A slash is used whenever you want to start a new node. E.g. //Sales.Customer/Sales.Customer_Order/Sales.Order. This query follows the path from the entity ‘Customer’ to the entity ‘Order’ over the association ‘Customer_Order’. A query can be expanded by slashes and nodes for as long as there are potential associations available in the domain model.
[ ] A constraint is always written between brackets. E.g. //Sales.Customer[TotalAmount > 1000]. The attribute being constrained is TotalAmount and the constraint is >1000. Only customers who have spent more than € 1000,- will be retrieved.
( ) Constraints can be grouped by parentheses. See this page for more information.
