PDF to XML using iTextsharp

Here is the very simple way of creating the XML from PDF document. I used Form fields in the PDF document. Then using the iTextsharp, I looped through the Acrofields or Form fields and created the flat XML document out of it. You can customize to create more complex structures if need be.

XmlDocument doc = new XmlDocument();
PdfReader reader = new PdfReader(@"C:\Input.pdf");
AcroFields fields = reader.AcroFields;
doc.LoadXml(string.Format("<{0}/>", root));
foreach (string keyName in fields.Fields.Keys)
{
AcroFields.Item item = fields.GetFieldItem(keyName);
XmlElement elt = doc.CreateElement(keyName);
elt.InnerXml = "<![CDATA[" + fields.GetField(keyName) + "]]>"";
doc.DocumentElement.AppendChild(elt);
}
doc.Save(@"C:\output.xml");
