You can choose whether to parse the file using the 'iternodes' iterator, an 'xml' selector, or an 'html' selector. In most cases, it's convenient to use iternodes, since it's a faster and cleaner. iternodesitemc|S)aThis overridable method is called for each result (item or request) returned by the spider, and it's intended to perform any last time processing required before returning the results to the framework core, for example setting the item GUIDs. It receives a list of results and the response which originated that results. It must return a list of results (items or requests). rselfresponseresultss 3lib/python3.11/site-packages/scrapy/spiders/feed.pyprocess_resultszXMLFeedSpider.process_resultss c|S)zYou can override this function in order to make any changes you want to into the feed before parsing it.
