| xpath | string | the XPath expression to wait for. |
| options | [WaitForSelectorOptions](./puppeteer.waitforselectoroptions.md) | <i>(Optional)</i> options to configure the visiblity of the element and how long to wait before timing out. |
Wait for the `xpath` to appear in page. If at the moment of calling the method the `xpath` already exists, the method will return immediately. If the xpath doesn't appear after the `timeout` milliseconds of waiting, the function will throw.
For a code example, see the example for [Frame.waitForSelector()](./puppeteer.frame.waitforselector.md). That function behaves identically other than taking a CSS selector rather than an XPath.
