Here is the code which is working for me.

     using System;
     using System.Collections.Generic;
     using System.Linq;
     using System.Web;
     using System.Web.UI;
     using System.Web.UI.WebControls;
     using iTextSharp.text;
     using iTextSharp.text.pdf;
     using System.IO;
     using System.Collections;
     using System.Text;
     using iTextSharp.text.xml;
     using iTextSharp.text.html;

     public partial class Default2 : System.Web.UI.Page
     {
           protected void Page_Load(object sender, EventArgs e)
           {
            //create document
            Response.Write(Server.MapPath("."));
            Document document = new Document();
            try
            {
              //writer - have our own path!!!
               PdfWriter.GetInstance(document, new FileStream(Server.MapPath(".") +         
                  "parsetest.pdf", FileMode.Create));
        document.Open();
        //html -text - kan be from database or editor too
        String htmlText = "<font  " +
        " color=\"#0000FF\"><b><i>Title One</i></b></font><font   " +
        " color=\"black\"><br><br>Some text here<br><br><br><font   " +
        " color=\"#0000FF\"><b><i>Another title here   " +
        " </i></b></font><font   " +
        " color=\"black\"><br><br>Text1<br>Text2<br><OL><LI>hi</LI><LI>how are u</LI> 
        </OL>";
        //make an arraylist ....with STRINGREADER since its no IO reading file...
        List<IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(htmlText), null);

        //add the collection to the document
        for (int k = 0; k < htmlarraylist.Count; k++)
        {
            document.Add((IElement)htmlarraylist[k]);
        }
        document.Add(new Paragraph("And the same with indentation...."));
        // or add the collection to an paragraph
        // if you add it to an existing non emtpy paragraph it will insert it from
        //the point youwrite -
        Paragraph mypara = new Paragraph();//make an emtphy paragraph as "holder"
        mypara.IndentationLeft = 36;
        mypara.InsertRange(0, htmlarraylist);
        document.Add(mypara);
        document.Close();

    }
    catch (Exception exx)
    {
        Console.Error.WriteLine(exx.StackTrace);
        Console.Error.WriteLine(exx.Message);
    }
 }
}

im getting exception at this line... the list The non-generic type 'iTextSharp.text.List' cannot be used with type arguments List<IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(htmlText), null);
when i used array instead of list i am getting exception Cannot implicitly convert type 'system.collection,generic.list to system.collections.arraylist
i corrected these issues but if any styles present in the html then itz not getting in the pdf
You just go here and you will get how to include css also while generating pdf from html today.java.net/pub/a/today/2007/06/26/…
its all about java, is it the problem with itextsharp..that the inline styles never come..?
