Description
The functx:has-element-only-content function returns true if the element has only child elements, with no direct textual (character data) content other than whitespace.
Technically, when a schema is not in use, the spaces and line breaks used to pretty-print XML documents do count as text nodes. However, for convenience, this function ignores them.
