Implementation Guide

Now, let’s delve into the core functionality of extracting text as HTML using GroupDocs.Parser.

Extracting Text as HTML

This feature allows you to convert document content into HTML format with ease. Here’s how:

Overview

The GroupDocs.Parser library facilitates extracting text from documents in various formats and converting it into HTML for further processing or display on web platforms.

Implementation Steps

Step 1: Load the Document

Begin by loading your target document using the Parser class.

// Load the document
using (Parser parser = new Parser(documentPath))
{
    // Check if text extraction is supported
    if (!parser.Features.Text)
    {
        Console.WriteLine("Text extraction isn't supported.");
        return;
    }
}
Step 2: Extract Text and Convert to HTML

Use the GetFormattedText method with HTML formatting options.

using (Parser parser = new Parser(documentPath))
{
    // Define text extraction options for HTML format
    FormattedTextOptions options = new FormattedTextOptions(FormattedTextMode.Html);

    // Extract formatted text as HTML
    using (TextReader reader = parser.GetFormattedText(options))
    {
        string htmlContent = reader.ReadToEnd();
        
        // Output the extracted HTML content
        Console.WriteLine(htmlContent);
    }
}

Key Configuration Options

  • FormattedTextOptions: Customize how you want to extract formatted text. Here, we use FormattedTextMode.Html.

Troubleshooting Tips

  • Ensure your file path is correct and accessible.
  • Verify that the document format is supported by GroupDocs.Parser.
