Jsoup 从下拉菜单中选择元素

Question

I have been trying to access a specific element from a dropdown menu on a Steam leaderboard page. Is there a good way to access a specific 'option value'? I have tried the following code and it isn't grabbing any value (debugger shows levelName as "").

String url = "http://steamcommunity.com/stats/592300/leaderboards/1900835";
Document document = Jsoup.connect(url).get();
String levelName = document.select("div#leaderHeader > option:contains(1900822)").val();
System.out.println(levelName);

There are few mistakes in your code:

• :contains doesn't check attributes, but text generated by element. If you want to find <option value="1900822">someText</option> using value="1900822" then you can use [attr=value] selector like option[value=1900822] (without quotes)
• you used parent > child but <option ...> is child of <select ...> element, not <div id="leaderHeader"> . This div is its ancestor, but it is not parent, so remove that >
• I am not sure what you are trying to do with val() method here, but I am guessing you want to use text() .

So you probably want:

String levelName = document.select("div#leaderHeader option[value=1900822]").text();

Just notice that there are some non-breaking spaces   in result. You may want to replace them with simple spaces and after that trim leading and trailing ones.

levelName = levelName.replace((char)160,' ').trim();
