What problem does this workflow solve:
This workflow addresses the challenge of efficiently extracting content from web pages through HTTP requests, converting it into a manageable format (Markdown), and handling errors gracefully. It simplifies the process by allowing users to specify query parameters, manage page content length, and clean up unnecessary HTML tags. Additionally, it provides clear error messages if the input is incorrect, ensuring a smoother user experience.
Detailed explanation of the workflow process:
- Trigger: The workflow is manually triggered or executed by another workflow.
- Receive Query Parameters: It captures input parameters from the query string, converting them into a JSON object for easier manipulation.
- Configuration Setup: It establishes a maximum limit for the page length based on user-defined parameters or defaults to 70,000 characters.
- HTTP Request: The workflow performs an HTTP request to the specified URL, allowing for both full and simplified content retrieval.
- Error Handling: It checks for errors in the HTTP response, providing appropriate error messages if the query is invalid or if there are issues during the request.
- HTML Processing: Upon successful retrieval, it extracts the HTML body, removes unnecessary tags (like
<script>,<style>, etc.), and checks if the content needs to be simplified based on user preferences. - Markdown Conversion: The cleaned HTML content is converted to Markdown format, preserving essential structure while reducing complexity.
- Content Length Check: It verifies the length of the resulting Markdown content, returning an error message if it exceeds the defined limit.
- Final Output: The processed content is sent back as the final output, ready for further use or display.
