functx:has-empty-content
Whether an element has empty content
Description
The functx:has-empty-content function returns true if the element has no content at all (not even whitespace.) This is in contrast to the fn:empty function, which will return true for any element regardless of whether it has any content.
To test whether an element has any content besides whitespace, see the functx:all-whitespace function.
