How to traverse back to the parent node in the XML file by using Xpath(using XSLT) query?

Let us have a xml tree of depth N. I have traveresd the last node means i am at last note. Now i wanted to go back to some level up (say at N开发者_JS百科-3) in the xml tree from that last node.

Please let me know the syntax for the XPATH query so that i can reached at intended node in the xml tree.

ancestor::node()[3]

or

../../..
