functx:has-mixed-content

Whether an element has mixed content

Description

The functx:has-mixed-content function returns true if the element has mixed content, i.e. both child elements and 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.
