Dear sir,
Can we done this task by using normal lisp program instead of vlax program?

Yes we can. But laborious.

How to get the value from a selected text and put that value in to the attribute?

[@cyberCADsolutions]

Read the text content and update attribute using vla-put_textstring.

[@cyberCADsolutions]

vlax-invoke getattributes
vla-get-tagstring
vla-get-textstring
vla-put-textstring
(setq blk(car (entsel "
Select block object:")))
(setq attLst(vlax-invoke (vlax-ename->vla-object blk) 'getattributes))
(foreach att attLst
(setq tag(vla-get-tagstring att)
val(vla-get-textstring att)
)
(princ (strcat "
" tag "=" val))
(princ)
);for
;change height value to 15m
(foreach att attLst
(setq tag(vla-get-tagstring att)
val(vla-get-textstring att)
)
(if (= (strcase tag) "HEIGHT")
(vla-put-textstring att "20")
);if
);for
