How to know the group in doc

Hi, Do we have a way to know “The Fund III REIT 2, LLC” belongs to “1. Organization and Nature of the Business” and (“Principles of Consolidation”,“Basis of Presentation”,“Revenue and Expense Recognition”) belong to “2. Summary of Significant Accounting Policies” when we load the docx by

Aspose.Words.Document doc = new Aspose.Words.Document(sourceFile);

@985664960 You can loop through the paragraphs in the document and build the tiles hierarchy according to the paragraph styles.
I think the best way to achieve this is using DocumentVisitor.
