Read XML from a scoket

[Drago Velchev]

Hi,
I have a socket connection where messages are formatted as XML, i.e. each
message is in the form <msg>..</msg>.
Is there an easy way to get a XMLDocument for each message form the socket
stream?
I tried with XMLTextReader and the NetworkStream of the socket but the
reader blocks until the socket is closed.
Any help?
regards

Lets see some code. It sounds like you're on the right path but you
might need to add a "flush()" call in order to avoid buffering in your
stream but gimme your code, me wants it.

here it is
sock.Connect(addr);
NetworkStream strm = new NetworkStream(sock,false);
XmlTextReader rdr = new XmlTextReader(strm);
rdr.Read(); // the program blocks here until the sock is closed

or

sock.Connect(addr);
NetworkStream strm = new NetworkStream(sock,false);
XmlDocument xdoc = new XMLDocument();
xdoc.Load(strm); // it blocks here

The server is working ok and sends the xml messages to the client.

If you are using an 1.1 Sp1, there is a bug in the code. If you are using
1.1 RTM, it should be fine. Instead of directly passing the Networkstream to
the xmltextreader, can you consume it completely and hold it in memory as a
workaround? And then send that to the xmltextreader?

There is a bug with .NET SP 1.1 using XmlTextReader with networkStream.

It works for me:

MemoryStream ms = new MemoryStream();

StreamReader sr = new StreamReader(ns);

if (ns.DataAvailable)
{
char[] b = new char[512];
int nread = sr.Read(b, 0, 512);

ms.Write(System.Text.Encoding.ASCII.GetBytes(b, 0, nread), 0, nread);
ms.Seek(0, System.IO.SeekOrigin.Begin);

XmlTextReader reader = new XmlTextReader(ms);
if (reader.Read())
{
objXmlDocument.Load(reader);
}
}
