Extract formatted text from document page

GroupDocs.Parser provides the functionality to extract formatted text from document page by the GetFormattedText(int, FormattedTextOptions) method:

TextReader GetFormattedText(int pageIndex, FormattedTextOptions options);

Methods return an instance of TextReader class with the extracted text. FormattedTextOptions has the following constructor:

FormattedTextOptions(FormattedTextMode mode);

FormattedTextMode enumeration has the following members:

Member	Description
Html	Html format.
Markdown	Markdown format.
PlainText	Plain text format.

Here are the steps to extract a HTML formatted page text from the document:

Instantiate Parser object for the initial document;
Check if formatted text extraction is supported for the document;
Instantiate FormattedTextOptions with HTML text mode;
Call GetFormattedText(int, FormattedTextOptions) method with the page index and obtain TextReader object;
Read a text from reader.

The following example shows how to extract a document page text as Markdown text:

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Check if the document supports formatted text extraction
    if (!parser.Features.FormattedText)
    {
        Console.WriteLine("Document isn't supports formatted text extraction.");
        return;
    }

    // Get the document info
    IDocumentInfo documentInfo = parser.GetDocumentInfo();
    // Check if the document has pages
    if (documentInfo.PageCount == 0)
    {
        Console.WriteLine("Document hasn't pages.");
        return;
    }
   
    // Iterate over pages
    for (int p = 0; p < documentInfo.PageCount; p++)
    {
        // Print a page number 
        Console.WriteLine(string.Format("Page {0}/{1}", p + 1, documentInfo.PageCount));
        // Extract a formatted text into the reader
        using (TextReader reader = parser.GetFormattedText(p, new FormattedTextOptions(FormattedTextMode.Html)))
        {
            // Print a formatted text from the document
            // We ignore null-checking as we have checked formatted text extraction feature support earlier
            Console.WriteLine(reader.ReadToEnd());
        }
    }
}
