How to extract absolute URL from relative HTML links using Jsoup?

Question

I am using Jsoup to extract URL of an webpage. The href attribute of those URL's are relative like:

<a href="/text">example</a>

Here is my attempt:

Document document = Jsoup.connect(url).get();
Elements results = document.select("div.results");
Elements dls = results.select("dl");
for (Element dl : dls) {
    String url = dl.select("a").attr("href");
}

This works fine, but if I use

String url = dl.select("a").attr("abs:href");

to get the absolute URL like http://example.com/text, it is not working. How can I get the absolute URL?

Answer 1

You need Element#absUrl().

String url = dl.select("a").absUrl("href");

You can by the way shorten the select:

Document document = Jsoup.connect(url).get();
Elements links = document.select("div.results dl a");
for (Element link : links) {
    String url = link.absUrl("href");
}
