Examples
Shows how to get all text from the document.
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_Text();
// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "Aspose.one");
// Retrieve text
string text = string.Join(Environment.NewLine, oneFile.GetChildNodes<RichText>().Select(e => e.Text)) + Environment.NewLine;
// Print text on the output screen
Console.WriteLine(text);
