ruby-on-rails-4 - 如何使用 Feedzirra / Feedjira 跳过解析 RSS 提要中的提升图像内容

Question

我正在使用名为 feedjira 的 gem 来解析 rails 中的 rss 提要。

Feedjira::Feed.add_feed_class Feedjira::Parser::RSS
feed = Feedjira::Feed.fetch_and_parse site[:url]
news = feed.entries

例如，它返回以下汇总字段值

$50 million loan by a client to a senior executive, the Securities and  
Exchanges Commission said on Monday.<br clear='all'/><br/><br/>

function rss_refine_string($get_rtext){
    $get_rtext = str_replace(""", "", $get_rtext);
    $get_rtext = str_replace("&lt;", "<", $get_rtext);
    $get_rtext = str_replace("&gt;", ">", $get_rtext);
    return $get_rtext;
}
