Some Help needed

[weicheong]

Hi guys, i hav successfully retrieve xmpmetadata from a pdf file and load it in a memeory stream. My current problem is to create another function such that i can directly use the xmpmetadata from the stream and parse it through my xpathdocument reader function.

This is my code for extracting the xmpmetadata:
MemoryStream os = new MemoryStream();
FileStream fs = new FileStream(PdfFile, FileMode.OpenOrCreate);
PdfReader reader = new PdfReader(fs);
fs.Close();
byte[] streamBytes = reader.Metadata;
string meta = System.Text.ASCIIEncoding.ASCII.GetString(streamBy tes);

and this is my code to allow the xmpmetadata to parse through my method:

XPathDocument doc = new XPathDocument("securePdf_withXmp.pdf");
//craete navigator
XPathNavigator nav = doc.CreateNavigator();



XmlNamespaceManager ns = new XmlNamespaceManager(nav.NameTable);

I wish to know what code to put in at the top of the codes to allow the xmpmeta from the stream and put inside the xpathdocument



many thanks!
