As of my last update, headless_chrome, which is a Rust library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol, can interact with web pages similarly to how you would with Puppeteer in JavaScript or Selenium in Python. The element selection methods available to you in headless_chrome would typically rely on CSS selectors, which are widely supported across web automation and scraping tools.
In headless_chrome, you can use methods like find_element and find_elements to locate elements on the page using CSS selectors. Here's an example of how you might use these methods in Rust:
use headless_chrome::{Browser, LaunchOptionsBuilder, protocol::page::ScreenshotFormat};
fn main() -> Result<(), failure::Error> {
let browser = Browser::new(LaunchOptionsBuilder::default().build()?)?;
let tab = browser.wait_for_initial_tab()?;
tab.navigate_to("http://example.com")?;
tab.wait_until_navigated()?;
// Find an element using a CSS selector
let elem = tab.find_element("div.some-class")?;
// Perform actions with the element, e.g., clicking it
elem.click()?;
Ok(())
}
In this example, "div.some-class" is a CSS selector that selects a div element with the class some-class. You can use any valid CSS selector to locate elements, such as:
- Tag names:
div,span,a, etc. - Class names:
.class-name - IDs:
#element-id - Attribute selectors:
[attribute=value] - Pseudo-classes and pseudo-elements:
:first-child,::before, etc. - Combinations and complex selectors:
div > .some-class,#id .class-name:first-child, etc.
If you're familiar with CSS selectors from web development or from using tools like jQuery, you'll find that using selectors with headless_chrome in Rust is quite similar.
Please note that headless_chrome is a third-party library, and its features or API could change over time. Always refer to the latest documentation or the library's source code for the most up-to-date information.
