JSoup，删除元素

Question

Basically what I want to achieve is to remove the elements that have a colspan=2 and only leave the other Elements. I am actually trying it with this code but it's not working, any Ideas ? :)

So this is my Code:

try {
      docSpielTagSpiele = Jsoup.connect(url).get();
} catch (IOException ex) {
      Logger.getLogger(FullFrame.class.getName()).log(Level.SEVERE, null, ex);
}

Elements spieltagElements = docSpielTagSpiele.select("div#Content > div.rahmen > div.rahmenbody > table.Spiele > tbody > tr > td.Heim");
System.out.println(spieltagElements);
System.out.println("SIZE: " + spieltagElements.size());

System.out.println("------------------------------------------------------------------------");

Elements el = spieltagElements.select("td.Heim[colspan=2]").remove();

System.out.println(el);
System.out.println("SIZE: " + el.size());

System.out.println("------------------------------------------------------------------------");

System.out.println("ELEMENTS THAT NEED TO BE REMOVED");
Elements remove = spieltagElements.select("td.Heim[colspan=2]");
System.out.println(remove);
System.out.println("SIZE: " + remove.size());

and this is my output:

Thanks already :)

Your method works as it should. The elements are removed from the DOM, as explained in the documentation . The remove method does not empty the collection of elements that you prepared before. So spieltagElements will remain as it was. The document docSpielTagSpiele however does not contain the removed elements any more. To see that, you need to query the original docSpielTagSpiele again.
