Create Perl scripts as required below:
a) Create a script named select_by_attribute.pl that accepts the name of a LibML documentand the name of a particular attribute from the command line. (For example, if you have a library of songs, you might like to use the singer, or composer. If you have a video library, you might like to use the actor, actress, director or producer...etc. The script must print to standard output the particular attribute and call numbers of the item as selected by the particular attribute.
b) Create a script delete_description that accepts a LibML document name as its parameter (from the command line). The script should delete the descriptions of all the items and print the resulting document on standard output.
c) Create script count_items.pl that takes a LibML document and report the total number of items in the library. The output should be printed in the standard output in plain text. Note that some item may have more than one call number, meaning that there are more than one item of having the same attribute.
