class ItemLoader(itemloaders.ItemLoader):
A user-friendly abstraction to populate an :ref:`item <topics-items>` with data by applying :ref:`field processors <topics-loaders-processors>` to scraped data. When instantiated with a selector or a response it supports data extraction from web pages using :ref:`selectors <topics-selectors>`.
If no item is given, one is instantiated automatically using the class in
default_item_class.
The item, selector, response and remaining keyword arguments are
assigned to the Loader context (accessible through the context attribute).

~ItemLoader.add_xpath, ~ItemLoader.add_css,
or ~ItemLoader.add_value. |
| selector | The selector to extract data from, when using the
add_xpath, add_css, replace_xpath, or
replace_css method. |
| response | The response used to construct the selector using the
default_selector_class, unless the selector argument is given,
in which case this argument is ignored. |
| Method | __init__ |
