using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.xml;
using System.IO;
using Word = Microsoft.Office.Interop.Word;
using System.Xml;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string pdfTemplate = null;
if (ofdSelectPdf.ShowDialog() == DialogResult.OK)
{
// take the path of the pdf file.
pdfTemplate = ofdSelectPdf.FileName;
}
textBox1.Text = ListFieldNames(pdfTemplate);
textBox1.Select(0, 0);
}
//declaration of function to check whether a form is xfa or pdf form
public string ReadFieldnames(PdfReader reader)
{
AcroFields form = reader.AcroFields;
XfaForm xfa = form.Xfa;
StringBuilder sb = new StringBuilder();
sb.Append(xfa.XfaPresent ? "XFA form" : "AcroForm");
return sb.ToString();
}
//code to get the xml of the pdf in the textbox
private string ListFieldNames(string pdfTemplate)
{
this.Text += " - " + pdfTemplate;
// create a new PDF reader based on the PDF template document
PdfReader pdfReader = new PdfReader(pdfTemplate);
//checking the form is XFa form or not
String str = ReadFieldnames(pdfReader);
MessageBox.Show(str);
XfaForm xfa = new XfaForm(pdfReader);
System.Xml.XmlDocument doc = xfa.DomDocument;
if (!string.IsNullOrEmpty(doc.DocumentElement.NamespaceURI))
{
doc.DocumentElement.SetAttribute("xmlns", "");
System.Xml.XmlDocument new_doc = new System.Xml.XmlDocument();
new_doc.LoadXml(doc.OuterXml);
doc = new_doc;
}
StringBuilder sb = new StringBuilder();
var Xsettings = new System.Xml.XmlWriterSettings() { Indent = true
};
using (var writer = System.Xml.XmlWriter.Create(sb, Xsettings))
{
doc.WriteTo(writer);
}
return sb.ToString();
}
}
}

Page 514 of the book says the TaggedPdfReaderTool:
won't work for PDF documents that don't have any structure...
but it will work for most tagged PDF files.
So I guess your out of luck with an untagged PDF document.

There is another tool:
http://www.mobipocket.com/dev/pdf2xml/
However, it doesn't handle fields, or it doesn't show
any fields when run on:
http://www.irs.gov/pub/irs-pdf/f1040.pdf
Instead, it just puts the text in xml elements.
HTH.
