Question

I parse all TD elements of a webpage.
There is 1 TD element which seems to be empty.

EUR 1,00
EUR 2,00
empty  <--
EUR 3,00

How can i fix this and remove the empty item from arraylist (results)?

Thank you in advance.

My code:

 try {

          Document doc = Jsoup.parse(kpo);  
       // Get all td's 
          Elements waardes = doc.select("TBODY"); 
          Iterator<Element> postIt = waardes.select("td").iterator();
       // Iterator over those elements      
          //ListIterator<Element> postIt = waardes.listIterator(); 
          postIt.next();
          postIt.next();
          postIt.next();
          postIt.next();

          SearchResults sr1 = new SearchResults();
          //SearchResults sr2 = new SearchResults();

          while (postIt.hasNext()) { 

                sr1 = new SearchResults();
                // Add the game text to the ArrayList      
                sr1.setNaam(postIt.next().text()); 
                sr1.setWaarde(postIt.next().text());  
                results.add(sr1); 
          } 

          } catch (Exception e) { 
        // TODO Auto-generated catch block 
            e.printStackTrace(); 
          } 

          return results;

        } 

Edit:
I got it to work like:

while (postIt.hasNext()) {  

    String naam = postIt.next().text();
    String waarde = postIt.next().text();

    sr1 = new SearchResults();

    // Add the text to the ArrayList     
    if (!naam.trim().isEmpty() && !waarde.trim().isEmpty()) {
       sr1.setNaam(naam);
       sr1.setWaarde(waarde);
       results.add(sr1); 
    }

Just make sure that you already don’t add the SearchResults when the waarde is empty. This way you don’t need to fiddle afterwards with cleaning the one and other.

So, replace

sr1.setWaarde(postIt.next().text());  
results.add(sr1); 

by for example

String waarde = postIt.next().text();

if (!waarde.trim().isEmpty()) {
    sr1.setWaarde(waarde);  
    results.add(sr1);
}
