MATLAB: Send XML over TCP/IP

Question

Hello,

I am trying to interface with a custom instrument using TCP/IP. The instruments communication is done through the use of XML based messages. Is it possible to send XML over TCP/IP in MATLAB. The XML is enclosed in a STX character (2) and a ETX character (3) to make the message easy to recognize.

I can connect to the instrument using a client TCP/IP object no problem. Just struggling with the next step.

An example message is:

STX<FASCr>
<rq>12</rq>
<id>0</id>
<v>0</v>
</FASCr>ETX

I know MATLAB has a xmlwrite function, just wondering how to send that over TCP/IP.

Thanks,

J

Answer 1

str = xmlwrite(DOMnode) serializes the DOM node to a string.

Once you have the string then

fprintf(TheSocket, '%c%s%c', 2, str, 3)
