Agenty CSS Selector and REGEX extractor engine can be used to extract anything from the website content, but sometime you might want few fields to be included in your output result which is not the part of website source content.
For example you are scraping stock information of 100 companies from a stock website but also want a DateTime field should also be in your output result to see when a particular page was fetched and information was extracted.
So Agenty offers the built-in default fields to add in your agent for all those cases when needed :
How to add a DEFAULT Field
- Click on the Edit tab to edit your agent in agent editor (Create one using Chrome extension if you don’t have any agent, the DEFAULT fields can be added after the agent is created)
- Then go to Field and Collections section and click on Add field button to add a field
- Change the Type as DEFAULT
- Select the default field you want to add in From drop-down box as in screenshot below:
- Finally, Save the scraping agent configuration.
These steps will change the scraping agent configuration only and you’d need to re-run your agent to extract the default field value when the field is added or updated.
