Process HTML

The Process HTML node takes HTML content and processes it by extracting specific elements, cleaning unwanted code, converting formats, or restructuring the content. Think of it as having a web developer clean up messy code and extract exactly what you need.

This is perfect for content cleaning, data extraction, format conversion, or preparing HTML content for use in other systems or workflows.

How it works

The node takes raw HTML content and applies various processing operations to clean, extract, convert, or restructure it. You can focus on specific elements or process the entire HTML document according to your needs.

Setup guide

1. Get HTML Content: Use Get All HTML node or provide HTML content from other sources.
2. Choose Processing Operation: Select extract, clean, convert, or restructure based on your needs.
3. Set Target Elements: Specify which parts of the HTML to focus on using CSS selectors (optional).
4. Select Output Format: Choose HTML, text, or Markdown for the processed results.

Practical example: Content cleaning

Let’s clean HTML content by removing ads and scripts while extracting the main article content.

What you configure:

• Content: The raw HTML code you want to work on.
• Operation: Choose “clean” to remove things or “extract” to find things.
• Targets: Use selectors (like .main-content) to focus on specific parts.
• Filters: Choose to remove scripts, ads, or other unwanted elements.

What you get:

• Processed Content: The clean, simplified HTML code.
• Stats: How much the file size was reduced and what elements were removed.

Common settings

Setting	Purpose	When to Use
Extract	Pull out specific elements or content sections	When you need only certain parts of the HTML
Clean	Remove unwanted elements, scripts, and attributes	For content purification and security
Convert	Transform HTML to other formats (Markdown, text)	For cross-platform content use

Perfect for content work

This node is essential for content management, data extraction, and preparing HTML content for use in different systems while maintaining quality and security.

Troubleshooting

• No results: Check that your target elements exist in the HTML using the correct CSS selectors
• Missing content: Try using broader CSS selectors or process the entire HTML without targeting specific elements
• Formatting issues: Different output formats handle styling differently - choose the format that best suits your needs
