--- id: selectors title: "Element selectors" --- Selectors query elements on the web page for interactions, like [`method: Page.click`], and to obtain `ElementHandle` through [`method: Page.$`]. Built-in selectors auto-pierce [shadow DOM](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM). ## Working with selectors Selector describes an element in the page. It can be used to obtain `ElementHandle` (see [`method: Page.$`] for example) or shortcut element operations to avoid intermediate handle (see [`method: Page.click`] for example). Selector has the following format: `engine=body [>> engine=body]*`. Here `engine` is one of the supported [selector engines](./selectors.md) (e.g. `css` or `xpath`), and `body` is a selector body in the format of the particular engine. When multiple `engine=body` clauses are present (separated by `>>`), next one is queried relative to the previous one's result. Playwright supports various selector engines: * [Text] selectors, for example `text="Log in"` * [CSS] selectors, including the following extensions: - [Shadow piercing](#shadow-piercing) by default and [`:light`](#css-extension-light) pseudo-class - [`:visible`](#css-extension-visible) pseudo-class - [`:text`](#css-extension-text) pseudo-class - [`:has`](#css-extension-has) and [`:is`](#css-extension-is) pseudo-classes - [Position selectors](#css-extension-position), for example `button:right-of(article)` * [XPath] selectors, for example `xpath=//html/body/div` * [id selectors][id], for example `id=sign-in` * [Custom selector engines](./extensibility.md) For convenience, selectors in the wrong format are heuristically converted to the right format: - selector starting with `//` or `..` is assumed to be `xpath=selector`; - selector starting and ending with a quote (either `"` or `'`) is assumed to be `text=selector`; - otherwise selector is assumed to be `css=selector`. ```js // queries 'div' css selector const handle = await page.$('css=div'); // queries '//html/body/div' xpath selector const handle = await page.$('xpath=//html/body/div'); // queries '"foo"' text selector const handle = await page.$('text="foo"'); // queries 'span' css selector inside the result of '//html/body/div' xpath selector const handle = await page.$('xpath=//html/body/div >> css=span'); // converted to 'css=div' const handle = await page.$('div'); // converted to 'xpath=//html/body/div' const handle = await page.$('//html/body/div'); // converted to 'text="foo"' const handle = await page.$('"foo"'); // queries '../span' xpath selector starting with the result of 'div' css selector const handle = await page.$('div >> ../span'); // queries 'span' css selector inside the div handle const handle = await divHandle.$('css=span'); ``` ```python async # queries 'div' css selector handle = await page.query_selector('css=div') # queries '//html/body/div' xpath selector handle = await page.query_selector('xpath=//html/body/div') # queries '"foo"' text selector handle = await page.query_selector('text="foo"') # queries 'span' css selector inside the result of '//html/body/div' xpath selector handle = await page.query_selector('xpath=//html/body/div >> css=span') # converted to 'css=div' handle = await page.query_selector('div') # converted to 'xpath=//html/body/div' handle = await page.query_selector('//html/body/div') # converted to 'text="foo"' handle = await page.query_selector('"foo"') # queries '../span' xpath selector starting with the result of 'div' css selector handle = await page.query_selector('div >> ../span') # queries 'span' css selector inside the div handle handle = await div_handle.query_selector('css=span') ``` ```python sync # queries 'div' css selector handle = page.query_selector('css=div') # queries '//html/body/div' xpath selector handle = page.query_selector('xpath=//html/body/div') # queries '"foo"' text selector handle = page.query_selector('text="foo"') # queries 'span' css selector inside the result of '//html/body/div' xpath selector handle = page.query_selector('xpath=//html/body/div >> css=span') # converted to 'css=div' handle = page.query_selector('div') # converted to 'xpath=//html/body/div' handle = page.query_selector('//html/body/div') # converted to 'text="foo"' handle = page.query_selector('"foo"') # queries '../span' xpath selector starting with the result of 'div' css selector handle = page.query_selector('div >> ../span') # queries 'span' css selector inside the div handle handle = div_handle.query_selector('css=span') ``` ## Syntax Selectors are defined by selector engine name and selector body, `engine=body`. * `engine` refers to one of the supported engines * Built-in selector engines: [css], [text], [xpath] and [id selectors][id] * Learn more about [custom selector engines](./extensibility.md) * `body` refers to the query string for the respective engine * For `text`, body is the text content * For `css`, body is a [css selector](https://developer.mozilla.org/en/docs/Web/CSS/CSS_Selectors) Body format is assumed to ignore leading and trailing white spaces, so that extra whitespace can be added for readability. ### Short-forms For convenience, common selectors have short-forms: - Selector starting with `//` or `..` is assumed to be `xpath=selector` - Example: `'//html'` is converted to `'xpath=//html'`. - Selector starting and ending with a quote (either `"` or `'`) is assumed to be `text=selector` - Example: `'"foo"'` is converted to `'text="foo"'`. - Otherwise, selector is assumed to be `css=selector` - Example: `'div'` is converted to `'css=div'`. ### Chaining selectors Selectors defined as `engine=body` or in short-form can be combined with the `>>` token, e.g. `selector1 >> selector2 >> selectors3`. When selectors are chained, next one is queried relative to the previous one's result. For example, ``` css=article >> css=.bar > .baz >> css=span[attr=value] ``` is equivalent to ```js document .querySelector('article') .querySelector('.bar > .baz') .querySelector('span[attr=value]') ``` If a selector needs to include `>>` in the body, it should be escaped inside a string to not be confused with chaining separator, e.g. `text="some >> text"`. ### Intermediate matches By default, chained selectors resolve to an element queried by the last selector. A selector can be prefixed with `*` to capture elements that are queried by an intermediate selector. For example, `css=article >> text=Hello` captures the element with the text `Hello`, and `*css=article >> text=Hello` (note the `*`) captures the `article` element that contains some element with the text `Hello`. ## Best practices The choice of selectors determines the resiliency of automation scripts. To reduce the maintenance burden, we recommend prioritizing user-facing attributes and explicit contracts. ### Prioritize user-facing attributes Attributes like text content, input placeholder, accessibility roles and labels are user-facing attributes that change rarely. These attributes are not impacted by DOM structure changes. The following examples use the built-in [text] and [css] selector engines. ```js // queries "Login" text selector await page.click('text="Login"'); await page.click('"Login"'); // short-form // queries "Search GitHub" placeholder attribute await page.fill('css=[placeholder="Search GitHub"]'); await page.fill('[placeholder="Search GitHub"]'); // short-form // queries "Close" accessibility label await page.click('css=[aria-label="Close"]'); await page.click('[aria-label="Close"]'); // short-form // combine role and text queries await page.click('css=nav >> text=Login'); ``` ```python async # queries "Login" text selector await page.click('text="Login"') await page.click('"Login"') # short-form # queries "Search GitHub" placeholder attribute await page.fill('css=[placeholder="Search GitHub"]') await page.fill('[placeholder="Search GitHub"]') # short-form # queries "Close" accessibility label await page.click('css=[aria-label="Close"]') await page.click('[aria-label="Close"]') # short-form # combine role and text queries await page.click('css=nav >> text=Login') ``` ```python sync # queries "Login" text selector page.click('text="Login"') page.click('"Login"') # short-form # queries "Search GitHub" placeholder attribute page.fill('css=[placeholder="Search GitHub"]') page.fill('[placeholder="Search GitHub"]') # short-form # queries "Close" accessibility label page.click('css=[aria-label="Close"]') page.click('[aria-label="Close"]') # short-form # combine role and text queries page.click('css=nav >> text=Login') ``` ### Define explicit contract When user-facing attributes change frequently, it is recommended to use explicit test ids, like `data-test-id`. These `data-*` attributes are supported by the [css] and [id selectors][id]. ```html ``` ```js // queries data-test-id attribute with css await page.click('css=[data-test-id=directions]'); await page.click('[data-test-id=directions]'); // short-form // queries data-test-id with id await page.click('data-test-id=directions'); ``` ```python async # queries data-test-id attribute with css await page.click('css=[data-test-id=directions]') await page.click('[data-test-id=directions]') # short-form # queries data-test-id with id await page.click('data-test-id=directions') ``` ```python sync # queries data-test-id attribute with css page.click('css=[data-test-id=directions]') page.click('[data-test-id=directions]') # short-form # queries data-test-id with id page.click('data-test-id=directions') ``` ### Avoid selectors tied to implementation [xpath] and [css] can be tied to the DOM structure or implementation. These selectors can break when the DOM structure changes. ```js // avoid long css or xpath chains await page.click('#tsf > div:nth-child(2) > div.A8SBwf > div.RNNXgb > div > div.a4bIc > input'); await page.click('//*[@id="tsf"]/div[2]/div[1]/div[1]/div/div[2]/input'); ``` ```python async # avoid long css or xpath chains await page.click('#tsf > div:nth-child(2) > div.A8SBwf > div.RNNXgb > div > div.a4bIc > input') await page.click('//*[@id="tsf"]/div[2]/div[1]/div[1]/div/div[2]/input') ``` ```python sync # avoid long css or xpath chains page.click('#tsf > div:nth-child(2) > div.A8SBwf > div.RNNXgb > div > div.a4bIc > input') page.click('//*[@id="tsf"]/div[2]/div[1]/div[1]/div/div[2]/input') ``` ## CSS selector engine `css` is a default engine - any malformed selector not starting with `//` nor starting and ending with a quote is assumed to be a css selector. For example, Playwright converts `'span > button'` to `'css=span > button'`. Playwright augments standard CSS selectors in two ways, see below for more details: * `css` engine pierces open shadow DOM by default. * Playwright adds a few custom pseudo-classes like `:visible`. ### Shadow piercing `css:light` engine is equivalent to [`Document.querySelector`](https://developer.mozilla.org/en/docs/Web/API/Document/querySelector) and behaves according to the CSS spec. However, it does not pierce shadow roots, which may be inconvenient when working with [Shadow DOM and Web Components](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM). For that reason, `css` engine pierces shadow roots. More specifically, any [Descendant combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Descendant_combinator) or [Child combinator](https://developer.mozilla.org/en-US/docs/Web/CSS/Child_combinator) pierces an arbitrary number of open shadow roots, including the implicit descendant combinator at the start of the selector. `css` engine first searches for elements in the light dom in the iteration order, and then recursively inside open shadow roots in the iteration order. It does not search inside closed shadow roots or iframes. ```html
In the light dom
In the light dom, but goes into the shadow slot
In the shadow dom
  • Deep in the shadow
  • ``` Note that `` is not an html element, but rather a shadow root created with `element.attachShadow({mode: 'open'})`. - Both `"css=article div"` and `"css:light=article div"` match the first `
    In the light dom
    `. - Both `"css=article > div"` and `"css:light=article > div"` match two `div` elements that are direct children of the `article`. - `"css=article .in-the-shadow"` matches the `
    `, piercing the shadow root, while `"css:light=article .in-the-shadow"` does not match anything. - `"css:light=article div > span"` does not match anything, because both light-dom `div` elements do not contain a `span`. - `"css=article div > span"` matches the ``, piercing the shadow root. - `"css=article > .in-the-shadow"` does not match anything, because `
    ` is not a direct child of `article` - `"css:light=article > .in-the-shadow"` does not match anything. - `"css=article li#target"` matches the `
  • Deep in the shadow
  • `, piercing two shadow roots. ### CSS extension: visible The `:visible` pseudo-class matches elements that are visible as defined in the [actionability](./actionability.md#visible) guide. For example, `input` matches all the inputs on the page, while `input:visible` matches only visible inputs. This is useful to distinguish elements that are very similar but differ in visibility, however it's usually better to follow [best practices](#best-practices) and find another way to select the element. Consider a page with two buttons, first invisible and second visible. ```html ``` * This will find the first button, because it is the first one in DOM order. Then it will wait for the button to become visible before clicking, or timeout while waiting: ```js await page.click('button'); ``` ```python async await page.click("button") ``` ```python sync page.click("button") ``` * This will find a second button, because it is visible, and then click it. ```js await page.click('button:visible'); ``` ```python async await page.click("button:visible") ``` ```python sync page.click("button:visible") ``` Use `:visible` with caution, because it has two major drawbacks: * When elements change their visibility dynamically, `:visible` will give upredictable results based on the timing. * `:visible` forces a layout and may lead to querying being slow, especially when used with `page.waitForSelector(selector[, options])` method. ### CSS extension: text The `:text` pseudo-class matches elements that have a text node child with specific text. It is similar to the [text] engine. There are a few variations that support different arguments: * `:text("substring")` - Matches when element's text contains "substring" somewhere. Matching is case-insensitive. Matching also normalizes whitespace, for example it turns multiple spaces into one, trusn line breaks into spaces and ignores leading and trailing whitespace. * `:text-is("string")` - Matches when element's text equals the "string". Matching is case-insensitive and normalizes whitespace. * `button:text("Sign in")` - Text selector may be combined with regular CSS. * `:text-matches("[+-]?\\d+")` - Matches text against a regular expression. Note that special characters like back-slash `\`, quotes `"`, square brackets `[]` and more should be escaped. Learn more about [regular expressions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp). * `:text-matches("value", "i")` - Matches text against a regular expression with specified flags. ```js // Click a button with text "Sign in". await page.click('button:text("Sign in")'); ``` ```python async # Click a button with text "Sign in". await page.click('button:text("Sign in")') ``` ```python sync # Click a button with text "Sign in". page.click('button:text("Sign in")') ``` ### CSS extension: has The `:has()` pseudo-class is an [experimental CSS pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:has) that is supported by Playwright. ```js // Returns text content of an
    element that has a
    inside. await page.textContent('article:has(div.promo)'); ``` ```python async # Returns text content of an
    element that has a
    inside. await page.textContent("article:has(div.promo)") ``` ```python sync # Returns text content of an
    element that has a
    inside. page.textContent("article:has(div.promo)") ``` ### CSS extension: is The `:is()` pseudo-class is an [experimental CSS pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:is) that is supported by Playwright. ```js // Clicks a `. - Text body can be escaped with single or double quotes for precise matching, insisting on exact match, including specified whitespace and case. This means `text="Login "` will only match `` with exactly one space after "Login". Quoted text follows the usual escaping rules, e.g. use `\"` to escape double quote in a double-quoted string: `text="foo\"bar"`. - Text body can also be a JavaScript-like regex wrapped in `/` symbols. This means `text=/^\\s*Login$/i` will match `` with any number of spaces before "Login" and no spaces after. - Input elements of the type `button` and `submit` are rendered with their value as text, and text engine finds them. For example, `text=Login` matches ``. Malformed selector starting and ending with a quote (either `"` or `'`) is assumed to be a text selector. For example, Playwright converts `page.click('"Login"')` to `page.click('text="Login"')`. `text` engine open pierces shadow roots similarly to `css`, while `text:light` does not. Text engine first searches for elements in the light dom in the iteration order, and then recursively inside open shadow roots in the iteration order. It does not search inside closed shadow roots or iframes. ### id, data-testid, data-test-id, data-test selector engines Attribute engines are selecting based on the corresponding attribute value. For example: `data-test-id=foo` is equivalent to `css=[data-test-id="foo"]`, and `id:light=foo` is equivalent to `css:light=[id="foo"]`. [css]: #css-selector-engine [text]: #text-selector-engine [xpath]: #xpath-selector-engine [id]: #id-data-testid-data-test-id-data-test-selector-engines
