Style names/IDs vary by template, language, and custom styles; there is no stable, standard mapping. Outline level may be absent, so consistent extraction isn’t guaranteed. - text: Same as text_content - page_number: Not available. Pagination is a rendering/layout result (paper size, margins, fonts, images, printer settings); Apache POI does not perform layout computation. - position_index: A hierarchical index (Markdown-style) isn’t feasible without a reliable document tree and heading detection; Word’s body is effectively flat and heading detection is inconsistent. A simple global ordinal is possible. - parent_id: Not available. WordprocessingML does not provide an explicit AST with parent-child relationships for paragraphs. - child_ids: Not available for the same reason as parent_id; there’s no stable logical child list per element in Word. -- This is an automated message from the Apache Git Service.
