Extract hyperlinks from document page

GroupDocs.Parser provides the functionality to extract hyperlinks from document page by the GetHyperlinks(Int32) method:

IEnumerable<PageHyperlinkArea> GetHyperlinks(int pageIndex);

This method returns a collection of PageHyperlinkArea object:

MemberDescription
PageThe page that contains the text area.
RectangleThe rectangular area on the page that contains the text area.
TextThe hyperlink text.
UrlThe hyperlink URL.

Here are the steps to extract hyperlinks from the document page:

  • Instantiate Parser object for the initial document;
  • Check if the document supports hyperlink extraction;
  • Call GetHyperlinks(Int32) method with the page index and obtain collection of PageHyperlinkArea objects;
  • Iterate through the collection and get a hyperlink text and URL.

The following example shows how to extract hyperlinks from the document page:

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Check if the document supports hyperlink extraction
    if (!parser.Features.Hyperlinks)
    {
        Console.WriteLine("Document isn't supports hyperlink extraction.");
        return;
    }
    // Get the document info
    IDocumentInfo documentInfo = parser.GetDocumentInfo();
    // Check if the document has pages
    if (documentInfo.PageCount == 0)
    {
        Console.WriteLine("Document hasn't pages.");
        return;
    }
    // Iterate over pages
    for (int pageIndex = 0; pageIndex < documentInfo.PageCount; pageIndex++)
    {
        // Print a page number 
        Console.WriteLine(string.Format("Page {0}/{1}", pageIndex + 1, documentInfo.PageCount));
        // Extract hyperlinks from the document page
        IEnumerable<PageHyperlinkArea> hyperlinks = parser.GetHyperlinks(pageIndex);
        // 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();
        }
    }
}
