Item Loader Objects
We get an item loader object, by instantiating, the ItemLoader class. The ItemLoader class, present in the Scrapy library, is the scrapy.loader.ItemLoader. The parameters, for ItemLoader object creation, are –
- item – This is the Item class, to populate, by calling add_xpath(), add_css() or add_value() methods.
- selector – It is the, CSS or XPath expression selector, used to get data, from the website, to be scraped.
- response – Using default_selector_class, it is used to prepare a selector.
