Merge Fields in PDF using XML and itextsharp

Hi all,

 

I'm posting here to ask for a huge help from you..

I need to accomplish a task and I'm having some problems..

I need to implement a method to merge fields in a PDF with forms created in Adobe Life Cycle.

I'll receive the template PDF and a XML to populate the PDF and need to return the new filled file. 

The xml is something like this:

 

 

So, I have something like the following:

 

  private MemoryStream GeneratePDF(string m_FormName, XmlDocument oData)
        {
            PdfReader pdfTemplate;
            PdfStamper stamper;
            PdfReader tempPDF;
            Document doc;
            MemoryStream msTemp;
            PdfWriter pCopy;
            MemoryStream msOutput = new MemoryStream();
            
            pdfTemplate = new PdfReader(m_FormName);
            
            doc = new Document();
            pCopy = new PdfCopy(doc, msOutput);
            
            pCopy.AddViewerPreference(PdfName.PICKTRAYBYPDFSIZE, new PdfBoolean(true));
            pCopy.AddViewerPreference(PdfName.PRINTSCALING, PdfName.NONE);
            
            doc.Open();
            
            for (int i = 1; i < pdfTemplate.NumberOfPages + 1; i++)
            {
                msTemp = new MemoryStream();
                pdfTemplate = new PdfReader(m_FormName);
                
                stamper = new PdfStamper(pdfTemplate, msTemp);
                
                // map xml values to pdf form controls (element name = control name)
                foreach (XmlElement oElem in oData.SelectNodes("/form1/*"))
                {
                    stamper.AcroFields.SetField(oElem.Name, oElem.InnerText);
                }
                
                stamper.FormFlattening = true;
                stamper.Close();
                tempPDF = new PdfReader(msTemp.ToArray());
                ((PdfCopy)pCopy).AddPage(pCopy.GetImportedPage(tempPDF, i));
                pCopy.FreeReader(tempPDF);
               
            }
            doc.Close();

            return msOutput;
        }

 

 

Hope someone can help me.

 

Kind Regards,

GV
