document: Using visual cues for extraction of tabular data from arbitrary HTML documents We describe a method to extract tabular data from web pages . Rather than just analyzing the DOM tree , we also exploit visual cues in the rendered version of the document to extract data from tables which are not explicitly marked with an HTML table element . To detect tables , we rely on a variant of the well-known X-Y cut algorithm as used in the OCR community . We implemented the system by directly accessing Mozilla 's box model that contains the positional data for all HTML elements of a given web page .
