How to get page meta (title, description, images) like facebook attach url using Regex in .java

Answer 1

I use JSOUP to get a Document object, then use something like the below method to get tags for each property I'm looking for.

String findTag(Document document, String property) {
    String tag = null;
    String cssQuery = "meta[property='og:" + property + "']";
    Elements elements = document.select(cssQuery);

    if (elements != null && elements.size() >= 1) {
        tag = elements.first().attr("content");
    }
    return tag;
}

I used this often enough to where I decided to combine the fetching (with JSOUP) and parsing together into a library called ogmapper.
