Utilities

anytree.util.commonancestors(*nodes)

Determine common ancestors of nodes.

>>> from anytree import Node
>>> udo = Node("Udo")
>>> marc = Node("Marc", parent=udo)
>>> lian = Node("Lian", parent=marc)
>>> dan = Node("Dan", parent=udo)
>>> jet = Node("Jet", parent=dan)
>>> jan = Node("Jan", parent=dan)
>>> joe = Node("Joe", parent=dan)

>>> commonancestors(jet, joe)
(Node('/Udo'), Node('/Udo/Dan'))
>>> commonancestors(jet, marc)
(Node('/Udo'),)
>>> commonancestors(jet)
(Node('/Udo'), Node('/Udo/Dan'))
>>> commonancestors()
()

anytree.util.leftsibling(node)

Return Left Sibling of node.

>>> from anytree import Node
>>> dan = Node("Dan")
>>> jet = Node("Jet", parent=dan)
>>> jan = Node("Jan", parent=dan)
>>> joe = Node("Joe", parent=dan)
>>> leftsibling(dan)
>>> leftsibling(jet)
>>> leftsibling(jan)
Node('/Dan/Jet')
>>> leftsibling(joe)
Node('/Dan/Jan')

anytree.util.rightsibling(node)

Return Right Sibling of node.

>>> from anytree import Node
>>> dan = Node("Dan")
>>> jet = Node("Jet", parent=dan)
>>> jan = Node("Jan", parent=dan)
>>> joe = Node("Joe", parent=dan)
>>> rightsibling(dan)
>>> rightsibling(jet)
Node('/Dan/Jan')
>>> rightsibling(jan)
Node('/Dan/Joe')
>>> rightsibling(joe)
