I would like to have an IOC talk to hardware that communicates using

this? Is there a better method?

Hi Scott,

I would try to do this with StreamDevice. However, StreamDevice requires

that the general form of the message is always the same. In particular

if you have multiple values in one message, the values should always

come in the same order. In SOAP, you could in principle have arbitrary

order, and arbitrary numbers of values, too. But normally a device would

not change the format randomly.

On the other hand, an XML parser for EPICS may be an interesting exercise.
