CGI::Pretty</h2><p><a name="INDEX-1317" />Allowsusers of CGI to output nicely formatted HTML code by adding carriagereturns and indentations to HTML markup for easy readability. Forexample, the following code:</p><blockquote><pre class="code">#!/usr/local/bin/perl -wuse CGI qw(:all);my $query = CGI->new( );print $query->start_html( );print $query->table( TR( td( "foo" ) ) );print $query->end_html( );</pre></blockquote><p>outputs the following HTML: </p><blockquote><pre class="code"><?xml version="1.0" encoding="utf-8"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.0//EN" "http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd"><html xmlns="http://www.w3.org/1999/xhtml" lang="en-US"><head><title>Untitled Document</title></head><body><table><tr><td>foo</td></tr></table></body></html></pre></blockquote><p>which is ugly. You can make it prettier with CGI::Pretty: </p><blockquote><pre class="code">#!/usr/local/bin/perl -wuse CGI::Pretty qw( :html3 );my $query = CGI->new( );print $query->start_html( );# Print a table with a single data elementprint $query->table( TR( td( "foo" ) ) );print $query->end_html( );</pre></blockquote><hr width="684" align="left" /><div class="navbar"><table width="684" border="0"><tr><td align="left" valign="top" width="228"><a href="ch08_37.htm"><img src="../gifs/txtpreva.gif" alt="Previous" border="0" /></a></td><td align="center" valign="top" width="228"><a href="index.htm"><img src="../gifs/txthome.gif" alt="Home" border="0" /></a></td><td align="right" valign="top" width="228"><a href="ch08_39.htm"><img src="../gifs/txtnexta.gif" alt="Next" border="0" /></a></td></tr><tr><td align="left" valign="top" width="228">8.37.
