      ...
    )

#### Description [src]

Checks whether the `parent` has a hierarchy of children described by pair of ‘ns_href’ and ‘name’.

Note: It requires two `NULL`-s at the end of the arguments, because the `ns_href' can be`NULL`, thus it could not distinguish between no namespace href and the end of the hierarchy children, thus it stops only on the 'name' being`NULL`.
