Java: Extract img src from HTML

Here is an code snippet for extracting image src from html.

    private static final Pattern IMG_SRC_PATTERN = Pattern.compile("<img\\s+.*src\\s*=\\s*('|\")(.+?)\\1.+?>");

    public static List<String> extractImgSrces(final String content) {
        List<String> list = new ArrayList<>();
        final Matcher matcher = IMG_SRC_PATTERN.matcher(content);
        while(matcher.find()){
            list.add(matcher.group(2));
        }
        return list;
    }

The example usage is below.
In this example, you should only prepare HttpUtils.getStringContentsFromURL method, which is getting html from given url, for your self.

    public static void main(String[] args) throws URISyntaxException, IOException {
        extractImgSrces(HttpUtils.getStringContentsFromURL("http://www.google.com/", "utf-8")).stream().forEach(System.out::println);
    }
