searching for an xpointer implementation

i'm trying to find out if there's are any xpointer implementations
available (especially in java):  i've been scouring the web, but the only
thing i can seem to find is a reference to an Implementation with DSSSL at:

     http://www.drmacro.com/hyprlink/xlink

but the server doesn't seem to exist.

if there are no usable implementations i'll be implementing a program to
extract a section of an xml document into a new document based on an
xpointer expression, but surely there must be something like this in
existance already?

any help would be appreciated.

regards,
