<DIV><FONT face=Arial><SPAN class=989143716-26082004>I know I can use something
like<FONT size=2> OGRSpatialReference->GetAttrValue("UNIT", 0), but that
will only return the first UNIT child node depending on where the root is.
Does anyone have this worked out. Code would be much
appreciated.</FONT></SPAN></FONT></DIV>
