解析 URL 以获取 hyber link 并将 hyber link 存储在单独的变量中

Question

您好，我正在 URL 解析 jsoup。当我解析 URL 时，我想获取 table 中的所有 href 并将每个 href 存储在单独的变量中。我的 Java 代码在这里

String url=null;
    try
    {       

        doc=Jsoup.connect("http://livechennai.com/powershutdown_news_chennai.asp").get();           
        Elements table=doc.select("#table13>tbody>tr>td>a");
        for(Element link:table){
            url=link.attr("abs:href");
            System.out.println(url);

        }

    }
    catch(IOException e){
        e.printStackTrace();
    }

我的输出如下所示

如何将每个 href link 存储在单独的变量中或任何其他方式都是可能的。帮我得到准确的答案。

Answer 1

这里是一个小片段，说明如何将 href 元素的 URL 添加到 List

List<String> hrefs = new ArrayList<>();
try {
    Document doc = Jsoup.connect("http://livechennai.com/powershutdown_news_chennai.asp").get();

    // more specific element specification, as in the question
    // Elements table = doc.select("#table13>tbody>tr>td>a");

    // less specific as mentioned by Jonathan
    Elements table = doc.select("#table13 a");

    for (Element link : table) {
        hrefs.add(link.attr("abs:href"));
    }
} catch (IOException e) {
    e.printStackTrace();
}
// here you can process all hrefs
for (String href : hrefs) {
    System.out.println(href);
}
