Due Date: February 21, 2000
(1) Write a Perl program, h4parse.pl, to extract from a html file, h4glossary.htm, all mortgage terms and their definitions. Study the format carefully so your program should work probably. Change HTML special characters in the file to regular txt regulars. Store the term as the key and the definition as the value of a Perl User Database, h4dbm. Note that the htm file is obtained from http://www.pamort.com/pamco/glossary.htm. Simplification has been applied to ease your job. Note that it is copyrighted so you should only use it as a homework.
(2) Write another Perl program h4search.pl to search for one keyword that appears in either the key or the value of the user database h4dbm created in (1). Here is a section of executing the program.
