                myXslTrans.Load("myXSLFile");
                myXslTrans.Transform("MyXMLFile", "TohtmlFIle"); 

//TohtmlFile is a html file to which i am storing the result of transformed xml. after debuging at this point when i check my html file it has the code only for headers, there is no data details.

System.Diagnostics.Process PROC = new System.Diagnostics.Process();
                PROC.StartInfo = new System.Diagnostics.ProcessStartInfo("TohtmlFile");// i am assiging the html file to be loaded in browser, which gives me only the headers attributes.
                PROC.Start();

problem is that it only shows headers, data is not shown in webbrowser. plz help needed
