Playwright Get DOM Tool

Gets the DOM content of the current page

Overview

This node, named "Playwright Get DOM Tool," retrieves the current Document Object Model (DOM) content of a web page from an existing browser session managed by Playwright. It is useful in automation workflows where you need to inspect or extract the full HTML structure of a page after navigation or interaction steps have been performed.

Common scenarios include:

  • Scraping or analyzing the HTML content of a page dynamically loaded via JavaScript.
  • Debugging or verifying the state of a webpage during automated browser testing.
  • Feeding the DOM content into further processing nodes such as AI tools for analysis or transformation.

For example, after navigating to a product page on an e-commerce site using a Playwright session, this node can capture the entire DOM to extract product details or check page elements.

Properties

Name Meaning
Session ID ID of the browser session to use. This identifies which active Playwright browser session the node should query to get the DOM content.

Output

The node outputs a JSON string under the response field containing:

  • A success flag (success: true) indicating the operation succeeded.
  • The full DOM content of the current page as a string (dom), representing the entire HTML markup at the moment of retrieval.

The output JSON looks like:

{
  "success": true,
  "dom": "<!DOCTYPE html><html>...</html>"
}

There is no binary data output.

Dependencies

  • Requires an active Playwright browser session identified by the provided Session ID.
  • Needs credentials for accessing the Playwright API service (an API key or authentication token).
  • Depends on internal operations that interface with Playwright to fetch the DOM content.

Troubleshooting

  • Common issues:

    • Invalid or expired Session ID: The node will fail if the specified browser session does not exist or has been closed.
    • Missing or incorrect Playwright API credentials: Authentication failures will prevent DOM retrieval.
    • Network or connectivity problems with the Playwright service.

  • Error messages:

    • "Failed to get DOM state: <error message>" indicates the node could not retrieve the DOM. Check that the session ID is correct and the Playwright service is reachable.

  • Resolutions:

    • Verify the session ID corresponds to an active Playwright session.
    • Ensure valid API credentials are configured.
    • Confirm network access to the Playwright API endpoint.
