Thanks for reply,
actually, i've tried this way with following code:
Item item = form.getFieldItem(key);
for(int ii =0;ii<item.size();ii++){
PdfDictionary dict = item.getMerged(ii);
Object[] dictKeys= dict.getKeys().toArray();
sb.append("==============================================================").append("\n");
sb.append(key+":").append("\n");
for(int j =0;j<dictKeys.length;j++){
sb.append((PdfName)dictKeys[j] + " : " +
dict.get((PdfName)dictKeys[j])).append("\n");
}
sb.append("==============================================================").append("\n");
}
and get the follow result:
