get parent elements in xml with simplexml in php?

with `$element->children()` i cant get all the child elements of current element. but how can i get all the parent elements for current element with simplexml? lets say it looks like this: ``` <entity id=1> <name>apple</name> <entities> <entity id=2> <name>mac</name> <entities> <entity id=3> <name>safari</name> </entity> </entities> </entity> </entities> </entity> ``` if my current `$element` is `id=3`, i want to get the mac and apple entity ids. is this possible with simplexml cause i cant find any function allowing me to do this?
