Missing selectors in libwww 4.1b5 ?


I am missing selectors like HTAnchor_children in libwww 4.1b5.
They were present in 4.0. 

How am I supposed to find all
children of a specific anchor to load them or do what I want with them?
(was: HTAnchor_children)

How am I supposed to find the places a document is referenced?
(was: HTAnchor_sources)
