How to get absolute URL from relative URL using Jsoup?
Many of the websites load various resources like images and css using relative URLs. If you want to download these resources as well using Jsoup, you need to convert these relative URLs to absolute URLs.
Jsoup element class provides absUrl method which converts relative URLs to absolute URL using base URI.
1 | public String absURL(String attributeName) |
If the URL is already an absolute URL, it is returned as is. If it is relative URL, it is converted to absolute URL using base URI and returned.
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | package com.javacodeexamples.libraries.jsoup; import java.io.IOException; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; public class JsoupGetAbsoluteURLExample { public static void main(String[] args) { try{ Document document = Jsoup .connect("http://www.google.com") .userAgent("Mozilla/5.0") .timeout(10 * 1000) .get(); Elements elements = document.select("img[src]"); for(Element e : elements){ System.out.println("Relative URL: " + e.attr("src")); System.out.println("Absolute URL: " + e.absUrl("src")); } }catch(IOException ioe){ System.out.println("Exception: " + ioe); } } } |
Output
1 2 | Relative URL: /images/icons/product/chrome-48.png Absolute URL: http://www.google.co.in/images/icons/product/chrome-48.png |
You can also use attr method with “abs:” prefix with attribute name to get the absolute URL instead of absUrl method as given below.
1 | System.out.println("Absolute URL: " + e.attr("abs:src")); |
