javascript 如何显示来自其他站点的 RSS 提要

How to display RSS feeds from other sites

提问by ragebunny

I have been researching this topic for a few days now and i'm still non the wiser as on how to do it.

我已经研究这个话题几天了，但我仍然不知道如何去做。

I want to get an RSS feed from forexfactory.com to my website, i want to do some formatting on whats happening and i also want the latest information from them (Although those last two points can wait as long as i have some more or feed running).

我想从 forexfactory.com 获得一个 RSS 提要到我的网站，我想对正在发生的事情做一些格式化，我还想从他们那里获得最新信息（尽管最后两点可以等待，只要我有更多或提要跑步）。

Preferably I'd like to develop this from the ground up if anyone knows of a tutorial or something i could use?

如果有人知道教程或我可以使用的东西，我最好从头开始开发它？

If not i will settle for using a third party API or something like that as long as i get to do some of the work.

如果不是，我会满足于使用第三方 API 或类似的东西，只要我能做一些工作。

I'm not sure what it is but there is something about RSS that i'm not getting so if anyone knows of any good, probably basic tutorials that would help me out a lot. It's kind of hard going through page after page of google searches.

我不确定它是什么，但有一些关于 RSS 的东西我没有得到，所以如果有人知道任何好的，可能是基本的教程会对我有很大帮助。逐页浏览谷歌搜索有点困难。

Also i'm not to fussed on the language it's outputted in Javascript, PHP or HTML will be great though.

此外，我不会对它在 Javascript、PHP 或 HTML 中输出的语言大惊小怪，但会很棒。

Thanks for the help.

谢谢您的帮助。

I didn't incorporate the < TABLE > tags as there might be more than one article that you would like to display.

我没有合并 < TABLE > 标签，因为您可能想要显示不止一篇文章。

class RssFeed
{
    public $rss = "";

    public function __construct($article)
    {
      $this->rss = simplexml_load_file($article, 'SimpleXMLElement', LIBXML_NOERROR | LIBXML_NOWARNING);

      if($this->rss != false)
      {
        printf("<TR>\r\n");
        printf("<TD>\r\n");
        printf("<h3>%s</h3>\r\n", $this->rss->channel->title);
        printf("</TD></TR>\r\n");

        foreach($this->rss->channel->item as $value)
        {
          printf("<TR>\r\n");
          printf("<TD id=\"feedmiddletd\">\r\n");
          printf("<A target=\"_blank\" HREF=\"%s\">%s</A><BR/>\r\n", $value->link, $value->title);
          printf($value->description);
          printf("</TD></TR>\r\n");
        }
      }
    }
}
