5 Built-in Item Pipelines reference Here is a list of item pipelines bundled with Scrapy. File Export Pipeline class scrapy.contrib.pipeline.fileexport.FileExportPipeline This pipeline exports all Exporters . It supports the following settings: • EXPORT_FORMAT (mandatory) • EXPORT_FILE (mandatory) • EXPORT_FIELDS • EXPORT_EMPTY • EXPORT_ENCODING If any mandatory setting is not set, this pipeline automatically disabled. File Export Pipeline examples Here are some usage examples of the File Export Pipeline. To export all scraped items into a XML file: EXPORT_FORMAT = 'xml' EXPORT_FILE = 'scraped_items
