Import Object Info from a file

Would it be possible to do the following ?

When I open a iso file the object list contains the following name values for the object for example: Bn0001_prt or Bn0333_asm

1. Remove all values starting from the underscore in the name attribute ?

2. The Object list may contain 200 objects

3. Change the Object Type attribute for all objects to part and then import Object info for the objects in the list from a file

For examle:

Import data from a text file that contains the following

Name Quantity Remarks

Bn0001 2 N/A

Bn0333 1 N/A

Any help would be greatly appreciated.
