You have to put the directory containing the package into the pth-file. 
That's probably

c:\dev\XmlDB

in your case. Also, Python will stop at the first matching module or 
package; if you keep c:\python27\lib\site-packages\xmldb that will shadow 
c:\dev\XmlDB\xmldb.

%APPDATA%/Python/Python26/site-packages

may be a good place for the pth-file (I'm not on Windows and too lazy to 
figure out where %APPDATA% actually is. The PEP 
http://www.python.org/dev/peps/pep-0370/ may help)
