Java 8 lambda streams come in handy when parsing HTML with Jsoup and Lombok @builders

snippet.java

        Document doc = Jsoup.parse(...);

        doc.select("form#login").stream()
                .map(e -> e.attr("action"))
                .map(action -> find(action, LINK_ID_PATTERN).group(1))
                .filter(Objects::nonNull)
                .findFirst()
                .ifPresent(builder::id);

        content.select("div#datePublished").stream()
                .map(Element::text)
                .map(SiteScraper::parseLocalDateTime)
                .filter(Optional::isPresent).map(Optional::get)
                .findFirst().ifPresent(builder::published);
