HTML::Seamstress::Quickstart is a gentle introduction to HTML::Seamstress. Introduction This guide is designed to get you started with dynamically generating and modifying ("templating") HTML with HTML::Seamstress. We will work through several examples, with each one increasing your ability to work with Seamstress effectively. Sample files All the files for the samples are in the directory lib/HTML/Seamstress/Quickstart Pure TreeBuilder Welcome to the first example. This is our bare-bones example. Lets say we want to dynamically modify the following HTML: < html > < head > < title >Greetings< /title > < /head > < body > < h1 >Greetings< /h1 > Hello there < span id=name >person< /span >, your lucky number is < span id=lucky_number >666< /span > < /body > < /html > Lets not use Seamstress at all in this case. Remember Seamstress just makes using HTML::Tree more convenient when writing software - it is completely optional and totally non-magical. So heres the (admittedly verbose) pure TreeBuilder solution: use strict; use warnings; use HTML::TreeBuilder; my $name = Redd Foxx; my $number = 887; my $tree = HTML::TreeBuilder->new_from_file(html/greeting.html); my $name_elem = $tree->look_down(id => name); $name_elem->delete_content; $name_elem->push_content($name); my $number_elem = $tree->look_down(id => lucky_number); $number_elem->delete_content; $number_elem->push_content($number); print $tree->as_HTML(undef, ); Theres a convenience function in HTML::Element::Library which makes it easy to replace all the content of an element. This will make our script shorter. If we simply use Seamstress, its new_from_file() method will bless the HTML tree into a class which inherits from HTML::Element::Library, making it easy for us to shorten our program. So lets rework the example using bare-bones Seamstress..
