ParserType enum

Types of parsers available for data extraction.

Each parser type has specialized logic for extracting different kinds of data from HTML, JSON, or other sources:

  • element - Extract HTML elements
  • attribute - Extract attribute values from HTML elements
  • text - Extract text content from HTML elements
  • image - Extract image URLs and metadata
  • url - Extract and process URLs
  • urlParam - Extract URL parameters
  • table - Extract data from HTML tables
  • sibling - Extract sibling elements
  • strBetween - Extract text between two strings
  • http - Make HTTP requests to extract data
  • json - Extract and parse JSON data
  • jsonld - Extract JSON-LD structured data
  • jsonTable - Extract data from JSON table structures
  • json5decode - Parse JSON5 format data
  • staticVal - Return static values
  • returnUrlParser - Return URL-based data
  • empty - Return empty value, helpful for using parent data as a fallback
Inheritance
