The XmlException class represents an error
condition that has occurred within the Berkeley DB XML system. The
system throws an XmlException if an API method
call results in an error condition. Methods on this class may be
used to get further information regarding the exception. Some of
these include XmlException::what and
XmlException::getExceptionCode. This object is not thread-safe, and
can only be safely used by one thread at a time in an application.
