ii. What is the correct XML Processing Instruction for the inclusion of games.dtd in games.xml? [5 pts]
iii. Write suitable XSL code for transforming games.xml into games.html. games.html must be an HTML file that displays the contents of games.xml in the form of a table as shown below. The XSL code must be stored in games.xsl file. [10 pts]
iv. What is the correct XML Processing Instruction for the inclusion of games.xsl in games.xml? [5 pts]
Question 2
a) Good websites will always have a visible hit/visitor counter that saves as testament as to how popular the site is. Write a simple Perl script that implements a hit/visitor counter, visi-count.pl. This script must display the count in the form of a single-row, multi-column table with each cell containing a single digit of the count. Each cell must have a different-coloured digit, e.g. [20 pts]
b) Give the correct Server-Side-Include (SSI) command for the inclusion of visi-count.pl on an HTML web page. [5 pts]

iii. Find all counties with names beginning with K or ending in Y and add them to the array @gaa_winners.
iv. The contents of array @gaa_winners must be written into an XML file, county.xml with the following structure. All county names must be in lower case!!!

Password Assume the following SQL statements were used to create the members relation.DROP TABLE IF EXISTS `members`;CREATE TABLE `members` ( `firstname` varchar(15) NOT NULL default '', `lastname` varchar(15) NOT NULL default '', `email` varchar(30) NOT NULL default '', `phone` varchar(14) NOT NULL default '', `username` varchar(15) NOT NULL default '', `password` varchar(10) NOT NULL default '') ENGINE=InnoDB DEFAULT CHARSET=latin1; 1. Write HTML code for a registration form to collect a new member’s details and save them in the register database. [5 pts]2. Write a Perl/CGI script to process the data. The CGI script must generate an HTML page acknowledging the registration [15 pts] Question 5a) For the register database in question 4 (b), 1. Write an HTML page that accepts a member’s login details, i.e. username and password [5 pts]2.
