Data class

Container for scraped data that includes both the source URL and extracted content.

This class serves as a wrapper for data extracted during web scraping operations. It maintains the relationship between the source URL and the extracted data, which is essential for tracking data provenance and handling relative URLs.

The obj field can contain any type of data:

  • HTML elements (Element, List<Element>)
  • Text content (String)
  • Structured data (Map, List)
  • Parsed JSON data
  • Any other extracted content
