# CustomQueryHandler interface
|
|
|
|
Contains two functions `queryOne` and `queryAll` that can be [registered](./puppeteer.registercustomqueryhandler.md) as alternative querying strategies. The functions `queryOne` and `queryAll` are executed in the page context. `queryOne` should take an `Element` and a selector string as argument and return a single `Element` or `null` if no element is found. `queryAll` takes the same arguments but should instead return a `NodeListOf<Element>` or `Array<Element>` with all the elements that match the given query selector.
