XMLWorker：找到無效的嵌套標記div，預計結束標記img

我只是想使用XMLWorker將圖像添加到我的PDF文檔中。但由於某種原因，它想要一個密切的img標籤。但即使我把它放在它仍然失敗。XMLWorker：找到無效的嵌套標記div，預計結束標記img

C＃代碼

 Byte[] bytes; 
     using (var ms = new MemoryStream()) 
     { 
      using (var doc = new Document(PageSize.A4.Rotate())) 
      { 
       using (var writer = PdfWriter.GetInstance(doc, ms)) 
       { 

        //Open the document for writing 
        doc.Open(); 

        //Our HTML and CSS 

        string exampleHtml = @"<div style='position: relative; width: 100%'>" + 

               "<img src='/Content/images/certificate.jpg'><img>" + 

               "<div style='position: absolute; top: 100px; left: 100px; width: 800px; height: 550px; text-align: center;'>" + 
               "<h1>" + 
               "<img src='/Content/images/CertTitle.png' alt='CERTIFICATE PDF' style='width: 800px;'/>" + 
               "</h1>" + 


               "<p>" + 
               "The School certifies that<br/>" + 

               "<h2>FIRSTNAME LAST NAME TITLE</h2>" + 

               "has participated in the class titled<br />" + 

               "<h2>COURSCODE - COURSENAME</h2>" + 


               "This activity was designated for # Credit(s)&trade;" + 

               "</p>" + 




               "<div style='float: left; position: absolute; bottom: 50px;'>" + 
               "<i>Date issued: DATE<br/></i><img src='Content/images/ceo-signature.jpg' style='border-bottom: solid #000 1px;'>" + 
               "</div>" + 
               "</div>" + 

               "</div>"; 

        using (var srHtml = new StringReader(exampleHtml)) 
        { 

         //Parse the HTML 
         iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml); //right here is where it crashes ({"Invalid nested tag div found, expected closing tag img."} {"The document has no pages."} 
        } 


        doc.Close(); 
       } 
      } 

      bytes = ms.ToArray(); 
     } 

     var testFile = HttpContext.Server.MapPath("~/Content/documents/UserCertificates/test.pdf"); ; 
     System.IO.File.WriteAllBytes(testFile, bytes); 

     Response.AddHeader("Content-Disposition", "inline; filename=test.pdf"); 
     return File(testFile, "application/pdf");

我從來沒有使用結束的img標籤，所以我很好奇，如果我在這裏做什麼了嗎？

XMLWorker適用於XML。雖然HTML支持未封閉的標籤（如'img'標籤），但這不是有效的XML。您必須確保使用方法來確保您的「HTML」有效。這將是沒有什麼不同，你的「br」標籤，雖然它可能在HTML中作爲
，它會打破作爲無效的XML。 –
