Notes on the Saxon implementation
Available from Saxon 9.5, provided XPath 3.0 is enabled. Streaming for the
has-children()
function is implemented from Saxon 9.7; specifically, a call
on has-children()
is now motionless, so that the call does not consume the
content. This means, for example, that the call can appear as a predicate in a match
pattern. The implementation uses a tiny amount of look-ahead in the parsing pipeline.
