extracting data from xpdf form and posting to access

Question

Hi, any help would really be appreciated. i am busy with a project. from a pdf document when a user clicks the submit button it comes to my mail box in .xfdf format, i need to extract all the data entered and post it into ms access database. the code below is what i have but does not seem to work

 

 

public partial class readXML : System.Web.UI.Page

DataTable DTX = null; //Datatable for SQL server table
DataTable DT = null; //for catching XML data

string Natemis;
bool EmisFlag = false;

//and pass on to integrator

foreach (string str in filepaths)
{

//Console.WriteLine(str + "\n");
}

}
