网页抓取Java

Question

我正在尝试抓取网页以提取银行汇率，但面临一些问题。代码是：

public class Main {

    public static void main(String[] args) throws IOException {
        Document doc = Jsoup.connect("http://www.banki.ru/products/currency/cash/usd/tyumen~/#bank-rates").get();

        //this is what I'm trying to extract, but the block below "tr[]data-currencies-row" is generated by JavaScript
        Elements elements1 = doc.select("tr[data-currencies-row]");
        System.out.println(elements1.size());   //prints 0

        //this block below works fine
        Elements elements2 = doc.select("a[class^=font-bold]");
        System.out.println(elements2.size());   //prints 3
    }
}

如何导航到“ tr [data-currencies-row]”标签？
