String manipulation & PDF output file

Question

First of all, thank you for trying to help me. It should be simple (I think I am only missing something)
I have a htm file that it’s used to produce a pdf file and gets date from a screen selection
It is about string manipulation (extraction a substring that starts with “[“ from a string and displaying the result )
Example instead of Van5[15] it’s supposed to display Van

(Note: data for [RoomName], [ClassName]are variables that comes from a previous screen)
The code is correct and verified on jsfiddle.net . The problem is, this HTM file that it is used to create the PDF output file displays on top the content between script tags;
function extract()
{
var str = "Van5 [14]";
return str.substring(0, str.lastIndexOf("["));
}
document.getElementById("demo").innerHTML = extract();
My question is, how to display the result(Van5) of this function on PDF file, not the content between tags

What I have tried:

HTML

<html>
<body>
<table>
        <tr>        
            <td colspan="2" style="text-align:center; font-size:80; font-family:Verdana; font-weight:bold;border:1px solid Black;">
                &nbsp;</td>
        </tr>
        <tr>
            <td colspan="2" style="text-align:center; font-size:60; font-family:Verdana; font-weight:bold;border:1px solid Black;">
                [RoomName]            

<p id="demo"></p> 
</td>
        </tr>
 <tr>
            <td colspan="2" style="text-align:center; font-size:29;font-family:Verdana;font-weight:bold;border:1px solid Black;">
                [ClassName]
            </td>
        </tr>
        
      
       
    </table>	

<script>
function extract() {
 var str = "Van5 [14]";
 return str.substring(0, str.lastIndexOf("["));    

}	
document.getElementById("demo").innerHTML = extract();
</script>
</body>
</html>

Maybe it is useful to mention, it uses iTextSharp, a .NET PDF library for creating the PDF file (from this HTMl fle)

no need of <.![CDATA[
and function extract() should be
function extract() {
var str=[RoomName]; return str.substring(0, str.lastIndexOf("["));

C#

I solve this task by myself. I just added the code between comments(//Remove square brackets..//) to the .cs file. For anyone that might need help with this topic, I am adding the code snippet here:

if (ReportList.Count > 0)
            {
                PdfWriter writer = PdfWriter.GetInstance(Report, new FileStream(FullPath, FileMode.Create));
                Report.Open();
                try
                {
                    if (ListRoomSign.Count > 0)
                        {                            
                             foreach (var ObjReportList in ReportList)
                            {
                                foreach (var ObjRoomSignList in ListRoomSign)
                                {.....
                                        string contents = System.IO.File.ReadAllText(HTMLFilePath);

                                        //Remove square brackets value from room name when printing room signs 
                                        if (ObjReportList.Location.Contains("["))
                                        {
                                            ObjReportList.Location = ObjReportList.Location.ToString().Substring(0, ObjReportList.Location.ToString().LastIndexOf("["));
                                        }
                                        //
                                        contents = contents.Replace("[RoomName]", ObjReportList.Location);
                                        var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), null);
                                        foreach (var htmlElement in parsedHtmlElements)
                                        {
                                            Report.Add(htmlElement as IElement);
                                        }
                                        Report.NewPage();                                        
                                }
							}	
                        }
						
                    Report.Close();
                }
                catch (Exception)
                {

                FullPath = string.Empty;
                }
            }
return FullPath;
