Converting object data to xdata using AutoLISP

问题：

Can I use AutoLISP to export object data to XData so that it can be easily read
in a DXF file?

解答：

Yes. The following example is one implementation.  It creates XData under
appname "MYODLIST" that is grouped by table, with records from that table nested
in that group. Note that because XData is limited to only 16KB, there is no
scope to handle overflow errors.

Here is sample XData that shows six records from three different tables that are
attached to this entity:

(-3 ("MYODLIST"
(1002 . "{")
(1000 . "test1")
(1002 . "{") (1070 . 0) (1000 . "num=1.0000") (1000 . "ordinal=First")
(1002 . "}")
(1002 . "}")

(1002 . "{")
(1000 . "test2")
(1002 . "{") (1070 . 0) (1000 . "num2=1.0000") (1000 . "ordinal=First")
(1002 . "}")
(1002 . "{") (1070 . 1) (1000 . "num2=2.0000") (1000 . "ordinal=Second")
(1002 . "}")
(1002 . "}")

(1002 . "{")
(1000 . "test3")
(1002 . "{") (1070 . 0) (1000 . "num3=1.0000") (1000 . "ordinal=First")
(1002 . "}")
(1002 . "{") (1070 . 1) (1000 . "num3=2.0000") (1000 . "ordinal=Second")
(1002 . "}")
(1002 . "{") (1070 . 2) (1000 . "num3=3.0000") (1000 . "ordinal=Third")
(1002 . "}")
(1002 . "}"))))

Here is the code:
