GroupDocs.Parser for .NET

It is our pleasure to announce the release of version 18.12 of GroupDocs.Parser for .NET. The latest version allows you to extract the tables from PDF documents. Furthermore, we have added the support of extracting text and metadata from text and presentation templates. For more details, please have a look at the release notes of version 18.12.

Features Introduced

Extracting Tables from PDF Documents

This feature is very useful when you want to extract only the tables form a PDF document. For extracting tables, TableAreaParser class is used. The instance of TableAreaParser class is available via property with the same name in PdfTextExtractor class. You can create the table bounds manually or let the API detect the layout in automatic mode using TableAreaDetector class.

For working example of this feature, please refer to this documentation article.

Extracting Text and Metadata from Text and Presentation Templates

GroupDocs.Parser now supports extracting text and metadata from the following text and presentation template formats:

  •     dotx (Template)
  •     dotm (Macro-enabled template)
  •     ott (OpenDocument Text Template)
  •     potx (Template)
  •     potm (Macro-enabled template)
  •     ppsm (Macro-enabled slideshow)
  •     pptm (Macro-enabled presentation)

The following code samples show how to extract text and metadata from templates.

// Extracting Text
void ExtractText(string fileName)
{
    // Extract a text from the file
    var text = Extractor.Default.ExtractText(fileName);
    // Print an extracted text
    Console.WriteLine(text);
}
// Extracting Metadata 
void ExtractMetadata(string fileName)
{
    // Extract metadata from the file
    var metadata = Extractor.Default.ExtractMetadata(fileName);
    // Print extracted metadata
    foreach (var m in metadata)
    {
        // Print a metadata key
        Console.Write(m.Key);
        Console.Write(": ");
        // Print a metadata value
        Console.WriteLine(m.Value);
    }
}

Enhancements

Detecting Type of Password-protected Office Open XML Documents

This feature allows detecting media type of the password-protected Office Open XML documents. To detect media type of encrypted Office Open XML document, Detect(Stream, LoadOptions) method is used. You can also use IPasswordProvider interface for batch document processing.
