You mean the dbxml example, right? There is no example named libxml
in the XSD distribution.

The dbxml example shows how to use the C++/Tree mapping on top of
the Berkeley DB XML database (see the README file in the dbxml
directory for details). As a result you need to have Berkeley DB XML
installed before you can build the dbxml example or your own code
that uses DB XML. The DbXml.hpp header file is provided by Berkeley
DB XML. For more information and to download Berkeley DB XML, see:

http://www.oracle.com/database/berkeley-db/xml/index.html

Now, if all you want is to serialize an object to XML in a file or
an in-memory string as opposed to an XML store managed by Berkeley
DB XML, then a better example would be 'library'. Also this topic
is covered in detail in the C++/Tree Getting Started Guide, Chapter 2,
Section 2.5, "Adding Serialization" and in Chapter 6, "Serialization":
