Implementation Guide

We’ll guide you through each feature step-by-step.

Feature 1: Check Document Support for Formatted Text Extraction

Overview: This feature determines if a document supports formatted text extraction before attempting any operations.

Step-by-Step Implementation:

Initialize Parser and Check Features
using System;
using GroupDocs.Parser;

public static void CheckDocumentSupport(string filePath)
{
    // Create an instance of the Parser class
    using (Parser parser = new Parser(filePath))
    {
        // Verify if formatted text extraction is supported
        if (!parser.Features.FormattedText)
        {
            Console.WriteLine("Document isn't supported for formatted text extraction.");
            return;
        }
    }
}

Explanation: This code snippet checks whether the document supports extracting text in a formatted manner. Performing this check avoids unnecessary processing on unsupported files.

Feature 2: Get Document Information

Overview: Retrieve essential information about the document, such as page count, which can be vital for further processing.

Step-by-Step Implementation:

Fetch Document Info
using System;
using GroupDocs.Parser;

public static void GetDocumentInfo(string filePath)
{
    // Create an instance of Parser class
    using (Parser parser = new Parser(filePath))
    {
        // Retrieve document information
        IDocumentInfo documentInfo = parser.GetDocumentInfo();

        // Confirm if the document contains pages
        if (documentInfo.PageCount == 0)
        {
            Console.WriteLine("Document hasn't got any pages.");
            return;
        }
    }
}

Explanation: This snippet retrieves and checks the number of pages in a document. Knowing the page count is essential for iterating over each page to extract text.

Feature 3: Extract Formatted Text from Document Pages as Markdown

Overview: Extract formatted text from each page using Markdown, preserving its styling during extraction.

Step-by-Step Implementation:

Iterate and Extract Text
using System;
using GroupDocs.Parser;
using GroupDocs.Parser.Options;

public static void ExtractFormattedTextAsMarkdown(string filePath)
{
    // Create an instance of Parser class
    using (Parser parser = new Parser(filePath))
    {
        // Get the document info
        IDocumentInfo documentInfo = parser.GetDocumentInfo();

        // Loop through each page to extract formatted text
        for (int p = 0; p < documentInfo.PageCount; p++)
        {
            // Extract formatted text into a reader in Markdown mode
            using (TextReader reader = parser.GetFormattedText(p, new FormattedTextOptions(FormattedTextMode.Markdown)))
            {
                // Read and print the formatted text from the page
                Console.WriteLine(reader.ReadToEnd());
            }
        }
    }
}

Explanation: This code iterates over each document page to extract its content in Markdown format. Using FormattedTextOptions, it ensures that the extracted text retains its original styling.
