GroupDocs.Parser is a powerful library that allows developers to parse and extract text from documents seamlessly. Whether you’re working with Word documents, PDFs, or other formats, GroupDocs.Parser simplifies the process of extracting structured content.

Prerequisites

Before diving into the code examples, ensure you have the following prerequisites:

• Visual Studio: Make sure you have Visual Studio installed on your system.
• GroupDocs.Parser for .NET: Download and install the GroupDocs.Parser library from here.
• Sample Document: Prepare a sample document (e.g., a Word document or PDF) that you’ll use for extracting HTML content.

Import Namespaces

First, import the necessary namespaces to access the GroupDocs.Parser functionality in your .NET project:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using GroupDocs.Parser.Options;

Step 1: Create an Instance of Parser Class

Initialize a Parser object by providing the path to your sample document:

// Create an instance of Parser class
using (Parser parser = new Parser("YourSampleFile.docx"))
{
    // Code to extract content will go here
}

Step 2: Extract HTML Content

Now, within the using block, utilize the GetFormattedText method to extract formatted text as HTML:

// Extract a formatted text into the reader
using (TextReader reader = parser.GetFormattedText(new FormattedTextOptions(FormattedTextMode.Html)))
{
    // Print a formatted text from the document
    // If formatted text extraction isn't supported, a reader is null
    Console.WriteLine(reader == null ? "Formatted text extraction isn't supported" : reader.ReadToEnd());
}

Conclusion

By following these steps, you can effectively use GroupDocs.Parser for .NET to extract HTML content from various document formats, empowering your applications with advanced text extraction capabilities.
