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.
This method works across navigation
```ts
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
let currentURL;
page
.waitForXPath('//img')
.then(() => console.log('First URL with image: ' + currentURL));
Promise which resolves when element specified by xpath string is added to DOM. Resolves to `null` if waiting for `hidden: true` and xpath is not found in DOM.
## Remarks
The optional Argument `options` have properties:
-`visible`: A boolean to wait for element to be present in DOM and to be visible, i.e. to not have `display: none` or `visibility: hidden` CSS properties. Defaults to `false`.
-`hidden`: A boolean wait for element to not be found in the DOM or to be hidden, i.e. have `display: none` or `visibility: hidden` CSS properties. Defaults to `false`.
-`timeout`: A number which is maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can be changed by using the [Page.setDefaultTimeout()](./puppeteer.page.setdefaulttimeout.md) method.
