Implementation Guide

Extract Text from TOC Using GroupDocs.Parser

Overview

This feature allows you to extract text associated with each item in a document’s table of contents, aiding navigation and access to specific sections efficiently.

Step 1: Set Up Your Document Directory Define the path where your document resides:

const string DocumentDirectory = "YOUR_DOCUMENT_DIRECTORY";

Step 2: Initialize Parser with Your Document Create an instance of the Parser class, pointing to your TOC-containing document.

using (Parser parser = new Parser(DocumentDirectory + "/SampleDocxWithToc.docx"))
{
    // Further steps will be executed within this block
}

Step 3: Retrieve and Iterate Through TOC Items Use the GetToc method to fetch the table of contents. Loop through each item, extracting the text.

IEnumerable<TocItem> tocItems = parser.GetToc();

foreach (TocItem tocItem in tocItems)
{
    using (TextReader reader = tocItem.ExtractText())
    {
        Console.WriteLine("----");
        Console.WriteLine(reader.ReadToEnd());
    }
}

Explanation:

  • GetToc(): Retrieves a collection of TOC items from the document.
  • ExtractText(): Extracts text associated with each TOC item, enabling processing as needed.

Troubleshooting Tips

  • Missing Documents: Ensure your file path is correct and accessible.
  • Empty TOC: Verify that the document contains a TOC.
  • Compatibility Issues: Use compatible .NET versions supported by GroupDocs.Parser.
