I do not have the time to study the gateway documentation to see what all it can output. It does appear that it can serve XML data from the webserver. If you can configure the webserver to serve the desired data in xml style, then you can set up your Do-More something like this:
1) OPENTCP GatewayConnection to the Gateways IP and the proper port.
2)STREAMOUT This should be a string something like this: "
http://10.0.0.21:80/MyConfiguresPageData.xml3) GatewayConnection.InQueue != 0 THEN STREAMIN to MyIncomingBufferName
4) CLOSE GatewayConnection
5) Trigger a new program/task to parse the xml data (We can help you work through this once you get the previous steps working).
