I am showing the data into a label like below.

 lit__Input.Text = ds.Tables[0].Rows[0]["lit_Input"].ToString();

How can I see an XML Data into Label or Other Controls.

The Label control in ASP.NET will be rendered as <span> tag with the value of the Text property. Your value seems to have html comment <!-- in front of it and therefore nothing will be shown when Label is rendered. You can check it if your right click on the page - View Source.

Use Server.HtmlEncode() to encode xml

lit__Input.Text = Server.HtmlEncode(ds.Tables[0].Rows[0]["lit_Input"].ToString());

Note, that the example above has invalid XML - it starts with <!--[if gte mso 9]><xml> and ends by QFormat="tru which is not valid XML. See how it looks like on the plain HTML page https://jsbin.com/geyexuzebe/edit?html,output - it breaks the entire page and you will not see "end of test" at the end of the page.

But its showing as it is data. I do not need xml to display and only display text data inside of xml. @smirnov

What is your complete XML? If you see your example above - it starts with <!--[if gte mso 9]><xml> and ends by QFormat="tru which is not valid XML

Actually I given some validation to ajax html editor so its storing like that ends tag. Is there any other solution. @smirnov

Again, your XML is not valid and might not be displayed properly because of its format. If you use ´lit__Input.Text = Server.HtmlEncode()´ - it works (shows plain XML but works). If you do not use ´Server.HtmlEncode()´ content is not shown and also the entire page looks broken, right? If true, it means it is due to XML content and therefore you have to check and correct it.
