Jsoup selector on RSS <link> tag returns empty string with .text() method (2 answers)

Closed 8 years ago.

我试图从 html 源代码中获得 RSS 链接。我使用 < a href=" http://jsoup. org/" rel=" nofollow" > Jsoup java 库查找 rs 链接。我写了一小部分代码来获取 RSS 链接, 但不幸的是, 并非所有网站都使用这个代码。下面是我的代码。

String url = "http://www.smashingmagazine.com/"; // not working
Document doc = Jsoup.connect(url).get();
Elements links = doc.select("link[type=application/rss+xml]");

if (links.size() > 0) {
    String rss_url = links.get(0).attr("href").toString();
} else {
    // RSS url not found
}

The above code is not working for all the websites. Please solve my problem. (I am trying to find RSS 2.0 links)

谢谢

答案是:

String url = "http://www.smashingmagazine.com/"; // not working
Document doc = Jsoup.connect(url).get();

Elements links = doc.select("link[type=application/rss+xml]");

if (links.size() > 0) {
    String rss_url = links.get(0).attr("abs:href").toString();
} else {....
    // RSS url not found
}

I hope it will be ok for you. It works with .attr(*"abs:*href")

厄图
