Cenoura com ervilha

Saladadealmeirão

Opcional：Quibe de PVT

Answer 1

我认为这就是你的意思：

    String url = "http://www.usp.br/coseas/cardapio.html";

    try {
        Document doc = Jsoup.connect(url).get();
        Elements rows = doc.select("tr pre");

        for (Element elem: rows) {
           System.out.println(elem.text());
        }
    }
    catch (IOException e) {
        e.printStackTrace();
    }

输出是：

SEGUNDA-FEIRA
Arroz/feijão preto/arroz integral
Copa lombo com molho de abacaxi
Virado de milho
Salada de acelga
Opcional: PVT à califórnia
Mexerica/refresco Valor calórico de 1 refeição 1195 kcal
