There is no distinction between TOC elements and other links inside an existing PDF documents as they are only defined at the time of PDF generation. Furthermore, you can extract text on the basis of regular expressions using Aspose.PDF. Would you please share your sample PDF document with us so that we can further check it and respond you accordingly.

There are no such sections defined in an existing PDF. Please note that headings/titles/header/footers are specified only at the time of PDF generation and once PDF is saved, they are become simple text elements. So, in your case, you can extract all text from PDF document and perform some string operations on extracted text to find/search your desired section. Please check following sample code snippet where text is extracted for first section i.e. TITLE PAGE:

Document doc = new Document(dataDir + "Symbiance-001.pdf");
TextAbsorber absorber = new TextAbsorber();
doc.Pages.Accept(absorber);
string extractedText = absorber.Text;

var start = extractedText.IndexOf("TITLE PAGE") + 12;
var match2 = extractedText.Substring(start, extractedText.IndexOf("CLINICAL PROTOCOL SYNOPSIS") - start);
