Extract Text from Tables in Aspose.Note

Introduction

In this tutorial, we’ll explore how to extract text from tables in Aspose.Note using C# with the .NET framework. Aspose.Note is a powerful API that allows developers to work with Microsoft OneNote files programmatically, enabling various operations such as creating, reading, manipulating, and converting OneNote documents.

Prerequisites

Before we begin, ensure you have the following:

1. Basic knowledge of C# programming language.
2. Visual Studio or any other C# IDE installed on your system.
3. Aspose.Note for .NET library. You can download it from here.
4. A sample OneNote document containing tables for text extraction.

Import Namespaces

To get started, let’s import the necessary namespaces:

using System.IO;
using Aspose.Note;
using System;
using System.Collections.Generic;
using System.Linq;

Step 1: Load the OneNote Document

The first step is to load the OneNote document into Aspose.Note:

// The path to the documents directory.
string dataDir = "Your Document Directory";

// Load the document into Aspose.Note.
Document document = new Document(dataDir + "Sample1.one");

Step 2: Get Table Nodes

Next, we need to get a list of table nodes from the loaded document:

// Get a list of table nodes
IList<Table> nodes = document.GetChildNodes<Table>();

Step 3: Extract Text from Tables

Now, iterate through each table node and extract text from them:

// Set table count
int tblCount = 0;

foreach (Table table in nodes)
{
    tblCount++;
    Console.WriteLine("table # " + tblCount);

    // Retrieve text
    string text = string.Join(Environment.NewLine, table.GetChildNodes<RichText>().Select(e => e.Text)) + Environment.NewLine;

    // Print text on the output screen
    Console.WriteLine(text);
}

Conclusion

In this tutorial, we’ve learned how to extract text from tables in Aspose.Note using C#. With the provided code snippets and explanations, you can now integrate text extraction functionality into your .NET applications effortlessly.
