ConfigurationBuilder.writeXmlConfiguration(OutputStream) only works if you have an ConfigurationBuilder that is populated somehow, you cannot use it on an arbitrary Configuration object. I tried to support that, but it turned out to be to difficult.
The built-in parsers for XML, JSON and YAML configurations are not based on ConfigurationBuilder (XML and JSON configuration parsers are older than ConfigurationBuilder, and YAML configuration parser is based on the JSON configuration parser). The properties configuration parser is newer and based on ConfigurationBuilder. (But I guess that will not help you.) Parsing an XML config file, transfer it to an ConfigurationBuilder and write out to another XML config file will not be easy since the XML config parser discards some information that is needed to reconstruct the config file.
