Hi Jasena,

In microflows, XPaths can be utilized in various ways to manipulate and retrieve data.

• Retrieve Objects: XPaths help us specify filters and conditions when fetching objects from the database in a microflow. They allow us to fetch specific objects based on their attribute values.
• Looping and Iteration: XPaths can be used in loops within microflows to go through a list of objects and perform actions based on certain conditions defined by XPaths.
• Attribute Access: XPaths help us access and change attribute values of objects in a microflow. For example, we can use an XPath to get or set the value of an attribute on an object.
• Association Traversal: XPaths enable us to navigate between different entities and retrieve related objects. This allows us to access and work with data from associated entities within a microflow.
• Aggregations: XPaths can be used in aggregate functions within microflows to perform calculations or fetch aggregated data based on specific conditions defined by XPaths.
• Validation: XPaths can be used to check conditions and validate data in a microflow to ensure it meets certain business rules.

Hope it helps!!!

While XPath is a full query expression including an entity.

//Sales.Customer[Name='Jansen']

In Mendix you usually only enter the XPath constraints, e.g. on a retrieve action for entity Customer, you enter only

[Name='Jansen']

I know that this may be a bit confusing when beginning with Mendix.
