What are the different XPath Axes?
Posted On: Feb 28, 2021
An XPath Axes defines the node-set relative to the current (context) node. It is used to locate the node that is relative to the node on that tree.
Different XPath Axes are listed below:
| S. N. | Axis name | Description |
| 1 | ancestor | This contains all the elements like grandparents, parents’ ancestors of the contextnode. In simple terms, this axis contains the root of the node. |
| 2 | ancestor-or-self | This refers to all the ancestor’s nodes and the root node itself (context node). |
| 3 | child | It refers to the child of the current node in the document during the traverse. |
| 4 | attribute | Refers to attributes of the current node in the specified document. |
| 5 | descendant | This refers to the descendants of the context node in the XML document. Namespaces or attributes are not included here. |
| 6 | descendant-or-self | This refers to the descendants of the context node in the XML document and the context node itself. |
| 7 | following | This contains all the nodes after the context node in a specific order but excluding the context node's descendants. |
| 8 | following-sibling | It contains the next subsequent nodes siblings followed by the root node. |
| 9 | self | Specifies their present node in the tree. |
| 10 | parent | It contains only one parent of the current node. |
| 11 | namespace | It refers to the namespace node of the root node with xmlns. And the axis is empty only when the context node is an element. |
| 12 | preceding | It contains all the nodes that come before the current tags(node). |
| 13 | preceding-sibling | The node traversed by the current context node to a previous sibling tag. |
