pip install parsify

Make sure you have your configuration file (usually handbook.json) ready.

import parsify as pf


# Create Parsify engine
ngn = pf.Engine(handbook='handbook.json')

# Run a single step
# Provide step name as an argument
# Should be in Engine.current_parser
# Should not have any "dynamic_variables" when custom using this method
# By default Engine.current_parser is the first parser in the Handbook
step_result = ngn.stepshot(step='get_products')
# print(step_result)

# Parse a single website (must be configured in "handbook.json")
# Provide scope name as an argument
scope_result = ngn.scopeshot(parser='example.com')
# print(scope_result)

# Run all the parsers that are configured in "handbook.json"
final_result = ngn.parse()
# print(final_result)

• Handbook file should start with "parser" key value of which is the array of parsers.
• Each parser in the array should have two keys:
  • "scope" - String: Name of the parser. Usually website name, i.e. "example.com".
  • "steps" - Array: Steps to parse.
• Each step should have at least following fields:
  • "name" - String: Unique name of the step. This field will make possible to access this step's results and dynamic variables in the proceeding steps (if needed).
  • "chain_id" - Integer: Steps with the same chain id will be executed as a sequence of steps on every iteration.
  • "url" - String: Target url of the request(s) for the current step.
  • "method" - String: Request method for the current step.
  • "output_path" String: Path of the result data in response. Use dots if it's multi-nested, for example, if needed result is in response -> "data" -> "products", "output_path" should be "data.products".
  • "output" Dictionary:
