如何使用Jsoup从CSS提取值？

Question

How can I extract "2015-06-18 15:24:48" from this code with JSoup?

<span class="review-time">Added <time datetime="2015-06-18 15:24:48">6 months ago</time></span>

I'm only able to extract "Added 6 months ago" by code below, but it's not what I need.

String date = element.getElementsByClass("review-time").text();

Answer 1

Since you already selected <span class="review-time">...</span> part now you can simply select <time..> element and read its datetime attribute. So your code can look like:

String date = element.getElementsByClass("review-time").select("time").attr("datetime");

Or you could even simplify it a little with one CSS selector like:

String date = element.select("span.review-time time").attr("datetime")

Answer 2

As simple as shown below. What you have to do is create a Document that stores the parsed html using Jsoup and then use the Document's select method to find the tag which is <time> and select its datetime attribute and print it.

String s = "<span class=\"review-time\">Added <time datetime=\"2015-06-18 15:24:48\">6 months ago</time></span>";

Document doc = Jsoup.parse(s);
Element timeTag = doc.select("time").first();

String dateTimeAttr= timeTag.attr("datetime");

System.out.println(dateTimeAttr);
