Display Condition

Sometimes it is necessary to display only certain table rows that meet a condition. In order to achieve this, the fo:id element is used as hint.

XF Rendering Server supports rendering documents that use the xf:display-condition extension.

This extension must be applied to fo:table-row.

Supported attributes:

•	after - the row will appear on every page where a table has areas, beginning with the page that contains the element with the specified id.

•	before - the row will be displayed on every page before the element with the specified id.

•	match - the row will only be displayed on the page with the specified id.

Example of usage for xf:display-condition="is-after(id)" :
