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:
Member | Description |
---|---|
Page | The page that contains the text area. |
Rectangle | The rectangular area on the page that contains the text area. |
Text | The hyperlink text. |
Url | The 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();
}
}
}
