Multi line form filling with iTextSharp - pdf

Question

I'm tring to fill a PDF file that has some different form fields, one of those field is a multi line field. I load the values from a txt file (I have to repeat this operation in batch so I've a single txt file for each pdf I've to fill)
My problem is with the \r\n present in the txt file... if I pass on each formfield it writes something as "My text\r\n on new line").
I've tried to use a stringbuilder and .AppendLine method and if I save it's content it correctly shows
My text
on new line
my input file is defined as
<map>
<campoModulo>lo_some_data</campoModulo>
<value>My text\r\non new line</value>
</map>
and here's the code I use to fill the pdf
internal void Process(string p)
{
string output = p.Replace(".pdf", "_new.pdf");
PdfReader reader = new PdfReader(p);
XmlDocument document = new XmlDocument();
document.Load("XML\\mapping.xml");
var items = document.SelectNodes("//map");
PdfStamper pdfStamper = new PdfStamper(reader, new FileStream(
output, FileMode.Create));
var acro = pdfStamper.AcroFields;
if (items.Count > 0)
{
foreach (XmlNode item in items)
{
var campo = item.SelectSingleNode("campoModulo").InnerText;
var valore = item.SelectSingleNode("value").InnerText;
acro.SetField(campo, valore);
}
}
pdfStamper.FormFlattening = true;
pdfStamper.Close();
}
What am I doing wrong?

You have to replace the \r\n for the actual control codes. Try:
text = text.Replace(#"\r\n", "\r\n");
