Convert from html string to pdf using itextsharp in asp.net

Question

I'm using iTextSharp in my project and using this method to parse html string to pdf

public static MemoryStream MakePdf(string htmlCode)
        {
            MemoryStream msOutput = new MemoryStream();
            TextReader reader = new StringReader(htmlCode);

            Document document = new Document(PageSize.A4, 30, 30, 30, 30);
            PdfWriter writer = PdfWriter.GetInstance(document, msOutput);
            HTMLWorker worker = new HTMLWorker(document);
            document.Open();
            worker.StartDocument();
            worker.Parse(reader); // EXCEPTION IN THIS LINE!!!!
            worker.EndDocument();
            worker.Close();
            document.Close();

            return msOutput;
        }

And it doesn't work for me. It throws an exception at selected line

URI formats are not supported.

How can I solve this problem?

P.S. Here is html I need to parse

HTMLWorker is deprecated in favor of XML Worker. That's the Java terminology for saying you're using functionality that is no longer supported because it has been replaced by new functionality. I don't know the corresponding C# terminology. — Bruno Lowagie

I've tried with new XmlWorker, XmlWorkerHelper, but it doesn't work again. — Chuck Norris

Well, maybe you've hit something that isn't supported (URI formats?) but it's hard to tell what isn't working based on the sole information that "it isn't working." We need more info to know what's going wrong. — Bruno Lowagie

I've edited my question and added my html too... Hopefully, you can find wrong part there... — Chuck Norris

That's strange. I can't help you with that until I start writing my next book. Currently I don't have the time for that (I'm rewriting the book about digital signatures). Also SO asks me to "please avoid extended discussions in comments." I guess you'll have to ask somebody else for help. — Bruno Lowagie

To solve this issue you can add Providers to your HTMLWorker using the SetProviders method which takes an IDictionary the HTMLWorker class has constants for the string keys. In your case have a look at the ILinkProvider and/or IImageProvider. These provide a way to handle the images and URLs inside of your HTML yourself, translating them into usable parts for the PDF.
