Where can you utilize XPaths in microflows?

The correct choice pertains to the usage of XPaths in the 'Retrieve' action within microflows. XPaths are utilized to fetch specific data from the Mendix database, and their main purpose is to define queries that filter results based on criteria set for attributes of entities. When you use the 'Retrieve' action in a microflow, you can precisely specify which objects to pull from the database, and XPaths allow for complex querying which can include conditions, relationships, and more.

In contrast, the other actions mentioned do not typically involve the use of XPaths. The 'Create' action is focused on adding new objects to the database without needing to filter based on existing data. The 'Change' action updates existing attributes of an object, and while it may refer to objects retrieved earlier, it does not inherently involve defining a query through XPath. The 'Delete' action simply removes objects, where the primary task is to specify which object to delete rather than creating a query for selection. Thus, XPaths are specifically applicable in the context of data retrieval, making the 'Retrieve' action the correct option.
