how to use linear path array command in autocad 2009

Hi, I'm trying to get the element count of each path array in a drawing that has a lot of them and export these values to a file. First I tried to do it through data extraction, but aparently the data extraction wizard doesn't allow to extract data from path arrays (or I have not been able to do so). So I turned to a lisp based solution. However I can't figure out how to get it. I expected to see that parameter (number of elements in a path array) as an entity code, but none of these looks like the object count of the path array nor path length or element spacing (which would allow to calculate the element count). I attach an example of the codes I get for a path array having 28 elements (path length 340,2 and element spacing 12,6): ( (-1 . <Entity name: 28777fee5f0>) (0 . "INSERT") (5 . "3362F") (102 . "{ACAD_REACTORS") (330 . <Entity name: 287073a1d50>) (102 . "}") (330 . <Entity name: 287774819f0>) (100 . "AcDbEntity") (67 . 0) (410 . "Model") (8 . "HOLES_LAYER") (100 . "AcDbBlockReference") (2 . "*U110") (10 0.0 10000.0 0.0) (41 . 1.0) (42 . 1.0) (43 . 1.0) (50 . 0.0) (70 . 0) (71 . 0) (44 . 0.0) (45 . 0.0) (210 0.0 0.0 1.0) ) I appreciate any help.
