Selecting objects with a certain xdata

I wanted to find a way to select all Mtext objects which has certain
xdata attached. I have an APPID and I can just select based on that. but
I am not sure how ot code the ssget function to only select mtext
objects with that APPID. any help would be appreciated.

I try this but it gives me error
(ssget "_X" '((-3 . "GBBNCONDOC")))

(ssget "_X" '((-3 . "GBBNCONDOC")(8 . "A-ANNO-KEYN")))

the 1000 values change with object. i.e. 09220A-002 varies.

; error: bad SSGET list value


here is the dump of entity
Command: (setq entl (entget ename (list AppName)))
((-1 . <Entity name: 400e0820>) (0 . "MTEXT") (5 . "A0C") (102 .
"{ACAD_REACTORS") (330 . <Entity name: 400e0818>) (102 . "}") (330 .
<Entity
name: 400dbcf8>) (100 . "AcDbEntity") (67 . 0) (410 . "Model") (8 .
"A-ANNO-KEYN") (100 . "AcDbMText") (10 396.968 556.491 0.0) (40 . 9.0)
(41 .
144.0) (71 . 1) (72 . 1) (1 . "\\A1;BROWN COAT 3/4\". ") (7 .
"GBBN-DIMN")
(210 0.0 0.0 1.0) (11 1.0 0.0 0.0) (42 . 91.8) (43 . 13.7143) (50 . 0.0)
(73 .
1) (44 . 1.0) (-3 ("GBBNCONDOC" (1000 . "09220A-002"))))

Thanks

 

Hi Nauman

(ssget "_X" '((-3 ("GBBNCONDOC"))))
