  • 0

I’m new to Jsoup and I’m trying to parse an html-file to find all the elements without an id. Until now I only have this code snippet:

            Document doc = Jsoup.parse(input, null);
        for (Element el : doc.getAllElements()) {
            hasId = el.hasAttr("id");
            if (!hasId) {
                idList.add(el.tagName());
            } else {
                log.info("id:" + el.attr("id"));
            }
        }

The elements with an id are found correctly. My problem is that I only want to scan the start elements if they have an id. Can I handle this with Jsoup?

    I’m not sure if I’m understanding your question correctly, but I think you just want to select all elements that don’t have an id attribute. If so, this should work:

    doc.select("*:not([id])")

    There’s a full list of selectors on the jsoup website.

    Update:

    Here’s a full example:

    import org.jsoup.Jsoup;
import org.jsoup.nodes.*;

public class Soup {
  public static void main(String[] args) {
    String data = "<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\"> <tr> <td class=\"reportheader\" align=\"left\" nowrap width=\"720\">Outside my Dreams</td> </tr> </table>";
    Document doc = Jsoup.parse(data);
    StringBuilder tags = new StringBuilder();
    for (Element el : doc.select("body *:not([id])")) {
      tags.append(el.tagName());
      tags.append(' ');
    }
    System.out.println(tags);
  }
}

    Running the above on my machine gives me this output: table tbody tr td

    Notice that I changed the query slightly: "body *:not([id])". Adding body at the front excludes the <html><title></title><body> ... </body></html> that Jsoup automatically adds when parsing the partial document in the data string.
