How to traverse back to the parent node in the XML file by using Xpath(using XSLT) query?
提问by Santosh kumar
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-3) in the xml tree from that last node.
让我们有一个深度为 N 的 xml 树。我已经遍历了最后一个节点意味着我在最后一个音符。现在我想从最后一个节点回到 xml 树中的某个级别(比如 N-3)。
Please let me know the syntax for the XPATH query so that i can reached at intended node in the xml tree.
请让我知道 XPATH 查询的语法,以便我可以到达 xml 树中的预期节点。
