### `subject:nth-ancestor(n)`
|
||||||
|
|
||||||
|
- Description: lookup the nth ancestor relative to the currently selected
|

node.
|
||||||
|
- Chainable: Yes.
|
||||||
|
- _subject_: Can be a plain CSS selector, or a procedural cosmetic filter.
|
||||||
|
- _n_: number, distance from the currently selected node.
|
||||||
|
- Examples:
|
||||||
|
- Existing filter: `fastbay.org##.detLink:has-text(VPN):xpath(../../..)` can be rewritten as `fastbay.org##.detLink:has-text(VPN):nth-ancestor(3)`

It is effectively a low-overhead equivalent to `:xpath(..[/..]*)`, as it avoids the need to create and execute [XPath expressions](https://developer.mozilla.org/docs/Web/XPath).
