How to populate data in XDP form?

All,

Requirement:

We need to be able to populate retrieved database data into GSA’s SF1034 form (Here is an example of fillable PDF form found on GSA web site: http://www.gsa.gov/portal/forms/download/115462).

Current Approach:

• Converted the PDF into XDP file using Adobe LiveCycle.
• Read the XDP file and replace the <chunk /> and <xfa:data /> sections.
• Generate PDF using convertXDPtoPDF.

Question:

I have successfully read the XDP and original PDF in my C# code, but my replacement of data is not successful.  I assume that I have replaced <xfa:data> incorrectly.  How should it be done properly?

Maybe I have the wrong approach to tackle this problem, if that’s the case please let me know as well.

Code:

I am trying to use the following C# code to insert data into XDP string and generate it as a PDF.

try

{

       using (StreamReader sr = newStreamReader(@"c:\Temp\PDF\SF1034-87.xdp"))

       {

             String line = sr.ReadToEnd();

             string pdfTemplate1 = @"c:\Temp\PDF\SF1034-87.pdf";

             FileStream stream1 = File.OpenRead(pdfTemplate1);

             byte[] pdf1 = newbyte[stream1.Length];

             stream1.Read(pdf1, 0, pdf1.Length);

             stream1.Close();

             // replace <chunk />

             line = line.Replace("<chunk />", "<chunk>" + Convert.ToBase64String(pdf1) + "</chunk>");

             // replace <xfa:data />

             line = line.Replace("<xfa:data />", "<xfa:data><topmostSubform><Page1><VoucherNumber>ABC123</VoucherNumber ></Page1></topmostSubform></xfa:data>");

             PDFUtilityServiceHelper _PDFUtilHelper1 = newPDFUtilityServiceHelper();

             // Convert the XDP file to a PDF document

             BLOB PDFin1 = newBLOB() { binaryData = System.Text.Encoding.UTF8.GetBytes(line) };

             BLOB result1 = _PDFUtilHelper1.convertXDPtoPDF(PDFin1);

             return result1.binaryData;

       }

}

catch (Exception e)

{

}

and the mentioned PDFUtilityServiceHelper is constructed as following:

privatePDFUtilityServiceSoapBinding _PDFUtil = newPDFUtilityServiceSoapBinding();

public PDFUtilityServiceHelper()

{

       _PDFUtil.Credentials = LiveCycleCredentials();

}

publicBLOB convertXDPtoPDF(BLOB inDoc)

{

       return _PDFUtil.convertXDPtoPDF(inDoc);

}
