* that match _isElement(), the normal variant will stop on every node
* except text nodes.
*
* To traverse the node and all of its children and siblings in Pyrex, call
* cdef xmlNode* some_node
* BEGIN_FOR_EACH_ELEMENT_FROM(some_node.parent, some_node, 1)
* # do something with some_node

* BEGIN_FOR_EACH_ELEMENT_FROM(parent_node, some_node, 1)

* END_FOR_EACH_ELEMENT_FROM(some_node)
