// Create a factory
ExtractorFactory factory = new ExtractorFactory();
// Create Zip container
ZipContainer zip = new ZipContainer(stream);
// Try to get "container.xml" entity from "META-INF" folder
Container.Entity containerEntry = zip.GetEntity("META-INF\\container.xml");
// If the entity isn't found
if (containerEntry == null)
{
    throw new GroupDocsTextException("File not found");
}
 
// Try to create a text extractor
TextExtractor extractor = factory.CreateTextExtractor(containerEntry.OpenStream());
try
{
    // Extract text (if the document type is supported)
    Console.WriteLine(extractor == null ? "Document type isn't supported" : extractor.ExtractAll());
}
finally
{
    // Cleanup
    if (extractor != null)
    {
        extractor.Dispose();
    }
}

.NET Text Extraction API – Enhancements

IPageTextExtractor Support for NoteTextExtractor

Following code snippets shows how to extract the text of OneNote document pages using IPageTextExtractor.

// Create a text extractor
NoteTextExtractor textExtractor = new NoteTextExtractor(stream);

// Check if IPageTextExtractor is supported
    IPageTextExtractor pageTextExtractor = textExtractor as IPageTextExtractor;
    if (pageTextExtractor != null)
    {
        // Iterate over all pages
        for (int i = 0; i < pageTextExtractor.PageCount; i++)
        {
            // Print a page number
            Console.WriteLine(string.Format("{0}/{1}", i, pageTextExtractor.PageCount));
            // Extract text from the page
            Console.WriteLine(pageTextExtractor.ExtractPage(i));
        }
    }

ITextExtractorWithFormatter Interface

Since version 17.12, we have added a feature that allows you to get or set document formatter via ITextExtractorWithFormatter interface. ITextExtractorWithFormatter interface has only one property.

DocumentFormatter DocumentFormatter { get; set; }

This property allows you to get or set document formatter of all types of formatted text extractors. Following code sample demonstrates its usage.

// If the extractor supports ITextExtractorWithFormatter interface
if (extractor is ITextExtractorWithFormatter) {
  // Set MarkdownDocumentFormatter formatter
  (extractor as ITextExtractorWithFormatter).DocumentFormatter = new MarkdownDocumentFormatter;
}
