iterationlayer Extract Article Text
Content aggregators and newsletter platforms use this recipe to extract clean article content from PDFs, Word documents, and saved web pages. Define fields for title, author, date, body, and summary — the parser pulls the content and ignores headers, footers, navigation, and sidebars.
