I want to extract "Title" and the URL, so I did this:

我想提取“标题”和 URL,所以我这样做了:

 Elements titleUrl = doc.getElementsByAttributeValue("class", "topic starter");
 String title = titleUrl.text();

And this works for the title, but for the URL I tried the following:

这适用于标题,但对于 URL,我尝试了以下操作:

 String url = titleUrl.html();
 String url = titleUrl.attr("a [href]");
 String url = titleUrl.attr("a[href]");
 String url = titleUrl.attr("href");
 String url = titleUrl.attr("a");

But no one works and I'm not able to get the URL.

但是没有人工作,我无法获得 URL。

Try this:

试试这个:

Element link = doc.select("td.topic.starter > a");
String url = link.attr("href");

You first select the aelement and then extract its attribute href.

您首先选择a元素,然后提取其属性href
