Depends. If your messages are never larger than 1K, this is enough. 
Otherwise, you have to collect the data, instead of parsing each chunk 
separately.

I suggest using the incremental parser in xml.etree.ElementTree, which 
allows you to push more data into the parser as it comes in. When done, 
call it's .close() method to retrieve the result.

You should also rethink your approach one more time. Are you sure that a 
raw socket is a good protocol for sending your messages? In many cases, a 
proper higher-level transport protocol like HTTP is much better suited. If 
you provide more details about what you are trying to do, others may be 
able to help you further.
