Scraping JavaScript-loaded HTML with Ruby on Rails and Nokogiri -

-

i trying scrape website product names.

my controller following:

page = nokogiri::html(open(page_url)) @items_array = page.css("li.item h3")

then displaying in view as:

<%= @items_array.each |item| %> <%= item.text %><br /><br /> <% end %>

the problem html loaded first 10 items. rest generated javascript. can't seem figure out how exactly.

any ideas on how scrape rest of content appreciated!

it won't work. nokogiri cannot scrape not on page, , can see (using "view source" on browser), part of list not html. how loaded irrelevant in case (probably using javascript).

best option ask them if expose api use (that make work easier).

scrapping fragile depend on exact layout of page.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
