Filtering data values
You can filter values and relationships from data value graphs using an XPath expression. An XPath filter can be configured and applied to individual foreign keys in a link configuration. These types of filters provide the convenience of configuration via the UI. However, there are limits to the available functions and operators.
Add an XPath expression to a link configuration's Path property. If conditions in a generated graph satisfy the expression, the add-on removes the corresponding nodes. As shown in the following image, you can use the Conditional Filter property to define an XPath filter:
Note
The add-on only supports XPath for fields on the target table, or a combination of the target and current tables. You cannot use the current table only. Additionally, the add-on validates the XPath statement when saving the record and blocks the save action if the statement is invalid.
The image below shows the result of applying the filter:
