Meanwhile I kept searching for a solution. I’m using WP3 and I traced back the problem to the XMLRPC implementation.
After a lot of trial and error I discovered that the problem is a faulty LIBXML2. This library is part of php5 and there is a bug in some versions provided which removes the leading ‘<‘ on tags.
There is a plugin to fix this but it wont work in my case. After contact with Jason Katzenback he provided me with an updated version that works without any problem.
Thanx
