Extract Hyperlinks from Document Page

Introduction

In this tutorial, we’ll explore how to use GroupDocs.Parser for .NET to extract hyperlinks from documents step-by-step. GroupDocs.Parser is a powerful library that enables developers to parse various document formats and extract text, metadata, and other elements.

Prerequisites

Before we begin, ensure you have the following:

Visual Studio: Install Visual Studio on your development machine.
GroupDocs.Parser Library: Download and reference the GroupDocs.Parser library. You can get it from here.
Sample Document: Prepare a sample document (e.g., DOCX, PDF) containing hyperlinks for testing.

Import Namespaces

First, include the necessary namespaces to use GroupDocs.Parser functionalities:

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

Step 1: Create Parser Instance

Instantiate the Parser class with the path to your sample document.

using (Parser parser = new Parser("YourSampleFile.docx"))
{
    // Code goes here...
}

Step 2: Check Hyperlink Extraction Support

Ensure that the document supports hyperlink extraction before proceeding.

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

Step 3: Retrieve Document Information

Get basic information about the document and check if it contains pages.

IDocumentInfo documentInfo = parser.GetDocumentInfo();
if (documentInfo.PageCount == 0)
{
    Console.WriteLine("Document has no pages.");
    return;
}

Step 4: Iterate Over Document Pages

Iterate through each page of the document.

for (int pageIndex = 0; pageIndex < documentInfo.PageCount; pageIndex++)
{
    Console.WriteLine($"Page {pageIndex + 1}/{documentInfo.PageCount}");
    // Extract hyperlinks from the current page
    IEnumerable<PageHyperlinkArea> hyperlinks = parser.GetHyperlinks(pageIndex);
    // Iterate over extracted hyperlinks
    foreach (PageHyperlinkArea hyperlink in hyperlinks)
    {
        Console.WriteLine($"Hyperlink Text: {hyperlink.Text}");
        Console.WriteLine($"Hyperlink URL: {hyperlink.Url}");
        Console.WriteLine(); // Blank line for readability
    }
}

Conclusion

In this tutorial, we’ve covered the basics of using GroupDocs.Parser for .NET to extract hyperlinks from documents. You learned how to initialize the parser, check for hyperlink support, retrieve document information, and iterate through document pages to extract hyperlinks efficiently.
