Extract Hyperlinks from Document Page Area

Introduction

In this tutorial, we will explore how to extract hyperlinks from a document’s specific page area using the GroupDocs.Parser for .NET library. GroupDocs.Parser provides powerful features for document processing, including hyperlink extraction. We’ll guide you through the process step-by-step, demonstrating how to implement this functionality in your .NET applications.

Prerequisites

Before we begin, ensure you have the following prerequisites:

Visual Studio: Installed on your system.
GroupDocs.Parser for .NET: Download and install from the website.
Sample Document: Prepare a document file (PDF, DOCX, etc.) containing hyperlinks for testing.

Import Namespaces

First, let’s import the necessary namespaces into your C# code:

using System;
using System.Collections.Generic;
using System.Text;
using GroupDocs.Parser.Data;
using GroupDocs.Parser.Options;

Step 1: Create Parser Instance

Initialize an instance of the Parser class with the path to your sample document.

// Create an instance of Parser class
using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Your code goes here...
}

Step 2: Check Hyperlink Extraction Support

Before extracting hyperlinks, ensure that the document format supports hyperlink extraction.

// Check if the document supports hyperlink extraction
if (!parser.Features.Hyperlinks)
{
    Console.WriteLine("Document doesn't support hyperlink extraction.");
    return;
}

Step 3: Define Extraction Options

Define the area on the page where you want to extract hyperlinks using PageAreaOptions.

// Create options for hyperlink extraction
PageAreaOptions options = new PageAreaOptions(new Rectangle(new Point(380, 90), new Size(150, 50)));

Step 4: Extract Hyperlinks

Use the defined options to extract hyperlinks from the specified page area.

// Extract hyperlinks from the document page area
IEnumerable<PageHyperlinkArea> hyperlinks = parser.GetHyperlinks(options);

Step 5: Iterate Over Extracted Hyperlinks

Iterate through the extracted hyperlinks and access their text and URLs.

// Iterate over hyperlinks
foreach (PageHyperlinkArea h in hyperlinks)
{
    // Print the hyperlink text
    Console.WriteLine(h.Text);
    // Print the hyperlink URL
    Console.WriteLine(h.Url);
    Console.WriteLine(); // Add a newline for readability
}

Conclusion

Congratulations! You’ve learned how to extract hyperlinks from a specific page area in a document using GroupDocs.Parser for .NET. This powerful library simplifies document processing tasks, allowing you to efficiently work with hyperlinks within your .NET applications.
