This article provides a complete, practical walkthrough of the Splitout Filter Automation Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Automate Sitemap Analysis and URL Filtering in n8n: A No-Code Guide
   
   Creating a custom crawler for sitemap analysis and targeted URL filtering typically involves some degree of programming. But with a powerful no-code tool like n8n, you can do it all visually — even parsing XML and filtering by file types such as PDFs — with zero lines of code. In this post, we’ll walk through an n8n workflow that reads a sitemap.xml file, converts it into JSON, and filters out only the URLs that end with “.pdf”. You can easily adapt this for other file types or filtering criteria.
   
   Let’s explore how it works and the components that make it tick.
   
   🎯 The Use Case
   
   Imagine you want to periodically scan a website’s sitemap and extract only certain types of content — say, downloadable PDF documents — for archiving, reporting, or further automation. Manually combing through those sitemaps isn't scalable. This is where n8n shines: it helps automate this process through a modular, visual workflow.
   
   🛠️ Workflow Overview
   
   This n8n workflow is aptly named “Read sitemap and filter URLs.” It breaks down into the following steps:
   
   - Retrieve the XML sitemap from a predefined URL.
   - Convert the XML data into JSON format.
   - Split the URLs into individual items.
   - Filter for specific file types (e.g., .pdf).
   - Output or utilize the results as needed.
   
   Here’s a breakdown of what each node does:
   
   1. Manual Trigger Node – “Test workflow”  
      This node acts as a starting point. You can trigger the entire workflow manually from within the n8n interface to test and refine it before scheduling or automating it further.
   
   2. Set Sitemap URL – “Set sitemap URL”  
      This node allows you to define the source XML sitemap. For example, the workflow uses “https://duckduckgo.com/sitemap.xml” by default, but you can input any publicly available sitemap XML link from any website you control or have permission to analyze.
   
   3. HTTP Request – “Get Sitemap”  
      This node fetches the sitemap.xml file from the URL set in the previous step. No authentication or headers are required for public sitemaps.
   
   4. XML Parser – “Convert Sitemap to JSON”  
      The raw sitemap data format is XML, which is not easy to filter directly. Therefore, we convert the XML into JSON so that each URL entry becomes more manageable and accessible through common n8n functions.
   
   5. Split Out – “Split Out”  
      The sitemap contains an array of URL objects. This node splits the JSON into individual pieces (per “url” node) that can be processed independently. This makes filtering much easier.
   
   6. Filter Node – “Filter URLs”  
      Here’s the logic portion. This filter checks each URL’s “loc” field and only allows entries that end with “.pdf” to pass through. This can easily be modified to search for any file extension — such as .docx, .jpg, or custom endpoints for APIs.
   
   📌 Bonus: Visual Annotations
   
   The workflow includes multiple "Sticky Note" nodes to make it beginner-friendly and self-explanatory. Each note explains what the adjacent component does, reminding you (or anyone you collaborate with) how and where to set key parameters like the sitemap URL and filter logic.
   
   🏗️ How to Customize
   
   Want to extract other file types or URL patterns?
   
   - Edit the “Filter URLs” node.
   - Change the condition to use “contains,” “starts with,” or even regex if you're feeling adventurous.
   - You can filter against other fields in the sitemap if needed (e.g., lastmod for date filtering).
   
   🔁 What Next? Possible Extensions
   
   Here are some ideas for extending this workflow:
   
   - Add a node to save the filtered results to Google Sheets or Notion.
   - Send a daily email of extracted PDFs via SMTP or Slack.
   - Schedule this automation using a Cron node for daily or weekly checks.
   
   🔐 Security Note
   
   The current setup works with public sitemaps. If you're trying to access a sitemap behind authentication, you’ll have to include credentials or headers in the “Get Sitemap” (HTTP Request) node, which is fully supported in n8n.
   
   🎉 Conclusion
   
   This simple yet powerful n8n workflow demonstrates how even complex XML parsing and file-type filtering tasks can be automated entirely without code. By customizing just two blocks — the sitemap URL and filter logic — you can tailor this process to your exact needs, whether you're monitoring educational resources, product documents, or research papers.
   
   With n8n’s flexibility and scalability, such tasks can evolve from tedious manual work into seamless background processes that just work. Happy automating!

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
