Generating HTML

• We've seen that we can use the CGI extension to generate HTML paragraph tags and so on.
• Additional functions can be requested at the time the CGI extension is loaded
• For advanced HTML features
• Example:

  use CGI qw(:html2 :form);

• This requests both the HTML standard version 2.0 elements and those that are used to generate forms.
• Documented in the CPAN description of importing CGI methods.

Examples

• Generate HTML code for a hyperlink:

  print $q->a( {href => "http://www.perl.com/"}, "Perl Home");

• Generate HTML code for a bullet list:

  print $q->ul( $q->li("Item 1"), $q->li("Item 2"), $q->li("Item 3"));

Review

Why might it be better to use these methods rather than just emitting the raw HTML yourself?
