HtmlUnit - Iterating through DomNodes looking for specific node

[Ryan Gray]

Hello all!

I'm using HtmlUnit to get some values from a website. I'm creating an HtmlPage called page, getting page.getDescendants() in an Iterable<DomNode> named pageDesc. Then I iterate through pageDesc and use the if statement to look for the specific node <tr class="away">. The if statement below looks like it should work, but does not. I have an alternative way in comments that DOES work, but I would prefer to access the node using the way not in comments.
Let me know if you need more info or you have an idea to try. Thanks!

public class Main{ 
 
        /** 
         * @throws IOException 
         * @throws MalformedURLException 
         * @throws FailingHttpStatusCodeException 
         */
 
        public static void main(String[] args) throws FailingHttpStatusCodeException, MalformedURLException, IOException { 
 
                final WebClient webClient = new WebClient(); 
                final HtmlPage page = webClient.getPage("http://mlb.mlb.com/mlb/scoreboard/index.jsp?c_id=det"); 
                 
                Iterable<DomNode> pageDesc= page.getDescendants(); 
                Iterator<DomNode> iterator = pageDesc.iterator(); 
                 
                while (iterator.hasNext()) { 
                        DomNode object = iterator.next(); 
                        if (object.getAttributes().getNamedItem("class").getNodeValue().toString().equals("away")) { 
                                System.out.println(object.getAttributes().getNamedItem("class").getNodeValue()); 
                        } 
//                  if (object.toString().equals("HtmlTableRow[<tr class=\"away\">]")) { 
//                          if (object.getAttributes().getNamedItem("class").getNodeValue().toString().equals("away")) { 
//                                  System.out.println(object.getAttributes().getNamedItem("class").getNodeValue()); 
//                          } 
//                  } 
                }   
                 
                webClient.closeAllWindows(); 
 
        } 
 
 
}

How about you only get the table rows from the page, then iterate over them using getAttribute("class")?

                final HtmlPage page = webClient.getPage("http://mlb.mlb.com/mlb/scoreboard/index.jsp?c_id=det"); 
                final DomNodeList<HtmlElement> getElementsByTagName("tr"); //get a list of all table rows
                for (HtmlElement row : DomNodeList)
                {
                    String className = row.getAttribute("class");
                    if ("away".equals(className))
                    {
                        /* do stuff for <tr class="away">
                           Note, you still have access to the row as an HtmlElement, so you can do
                           row.getElementsByTagName("td");
                           for example to get all the cells...
                        */
                    }
                }
