<?php
    $limite = 5;
    $xml = simplexml_load_file('http://g1.globo.com/dynamo/economia/rss2.xml') or die("erro carregar arquivo");
    $noticias = $xml->xpath(sprintf('/rss/channel/item[position() <= %d]', $limite));

    foreach ($noticias as $noticia) {
        $noticia->pubDate = date('d/m/Y');

        echo "
            <li>
                <div class=\"timeline-badge\"><i class=\"fa fa-check\"></i>
                </div>
                <div class=\"timeline-panel\">

                        </p>
                    </div>

                    <div class=\"timeline-body\">
                        <a href=\"$noticia->link\" target=\"_blank\">$noticia->title</a><br>
