我有以下 HTML。看input tag下面comment（问题的真正原因）。

<div class="col-xs-12 GPAMainForm">
  <div class="col-xs-10 col-xs-offset-1">
    <div style="border: 1px double black; padding: 2px">
      <div>
        <table class="table">
          <tr class="border">
            <td class="border">
              <label class="control-label">Company Name</label>
            </td>
            <td class="border">
               <input type="text" />
               <!--
               If I remove input tag, pdf gets generated else it show error like:
               `Invalid nested tag td found, expected closing tag input`
               -->
            </td>
          </tr>
        </table>
      </div>
    </div>
  </div>
</div>

而不是input tag我试图去<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

错误

找到无效的嵌套标记 td，预期结束标记输入

问题原因

但是当我看到解析的 html 时，我可以清楚地知道它以某种方式删除/并生成<input type="text>.

与<asp:textbox>它相同删除结束标签并生成

<input name="ctl00$MainContent$TextBox2" id="MainContent_TextBox2" type="text">

请帮忙。

                string htmlContent = TextBox1.Text.Replace("\r", "\n").Replace("\n", "");// you html code (for example table from your page)
                Document doc = new Document();

                cssResolver.AddCss(cssFile);


                CssAppliers ca = new CssAppliersImpl();
                HtmlPipelineContext hpc = new HtmlPipelineContext(ca);
                hpc.SetTagFactory(Tags.GetHtmlTagProcessorFactory());

                // PIPELINES
                PdfWriterPipeline pdf = new PdfWriterPipeline(doc, writer);
                HtmlPipeline htmlPipe = new HtmlPipeline(hpc, pdf);
                CssResolverPipeline css = new CssResolverPipeline(cssResolver, htmlPipe);

                XMLWorker worker = new XMLWorker(css, true);
                XMLParser p = new XMLParser(worker);
                StringReader sr = new StringReader(htmlContent);
                p.Parse(sr);
                doc.Close();

                Response.ContentType = "application/pdf";
                Response.AppendHeader("Content-Disposition", "attachment; filename=" + FileName + ".pdf");
                Response.TransmitFile(Server.MapPath(@"~\PDF\" + FileName + ".pdf"));
                Response.End();
            }
            catch (Exception ex)
            {
                Response.Write(ex.Message.ToString());
            }
