The best way to address the problem (if the goal is to get the code  
into log4cxx) is to experiment with log4j (and/or chainsaw) to see  
how they address the problem and then port any missing pieces into  
log4cxx.  log4cxx tries to keep itself aligned with the log4j code- 
base where possible.  I'm guessing the  
org.apache.log4j.net.XMLSocketReceiver in the log4j 1.3 code base  
would be the place to start.

For XML parsing, apr-util (part of the Apache Portable Runtime)  
provides a DOM-like XML parser that is used to parse the XML  
configuration files.  The underlying event parser used in Expat, but  
that isn't exposed through apr-util.
