Axes
Overview of the axis component of a query.
The axis component of a query determines the direction of the node selection in relation to the context node. An axis can be thought of as a directional query.
Note
The axis component of a query is not scalable when using item buckets and a large number of content items.
The following table lists some common axes:
Axes | Description |
|---|---|
ancestor | Returns all the ancestors of the context item (same as XPath). |
ancestor-or- self | Returns the context item and all the ancestors of the context item (same as XPath). |
child | (/*) returns all the children of the context item (same as XPath). |
descendant | (//*) returns all the descendants of the context item; a descendant is a child or a child of a child and so on (same as XPath). |
descendant- or-self | Returns the context item and all the descendants of the context item (same as XPath). |
following | Returns all the following siblings of the context node (same as following-sibling in XPath). |
parent | (..) returns the parent item of the context item (same as XPath). |
preceding | Returns all the preceding siblings of the context item (same as preceding-sibling in XPath). |
self | (.) returns the context item (same as XPath). |
