點擊的HtmlUnit HREF「圖像」

Question

任何想法如何點擊這個「形象」與HtmlUnit？

<a href="play.php?choose=2"> 
<div id="champbox" style="background-image: url(http:xxx.jpg);float:right;"></div></a> 

試過用的HtmlAnchor和XPath點擊它，但得到象這樣的錯誤：

java.lang.NullPointerException 

或

com.gargoylesoftware.htmlunit.ElementNotFoundException: elementName=[a] attributeName=[href] attributeValue=[play.php?choose=2]

我的代碼：

 //Webclient Options 
     final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_45); 
     webClient.getOptions().setRedirectEnabled(true); 
     webClient.getOptions().setThrowExceptionOnScriptError(false); 
     webClient.getOptions().setCssEnabled(false); 
     webClient.getOptions().setUseInsecureSSL(true);

    // Cut out the Login (better Overview) 

    HtmlAnchor anchor = page2.getAnchorByHref("play.php"); 
    HtmlPage page3 = anchor.click(); 
    System.out.println(page3.getTitleText()); 
    System.out.println(page3.getUrl()); 

    //To-Do: Click left or right Picture 

    /* 
    HtmlAnchor a1 = page3.getAnchorByHref("play.php?choose=2"); 
    System.out.println(a1.asXml()); 
    HtmlAnchor a2 = page3.getFirstByXPath("//a[@href='play.php?choose=2']"); 
    System.out.println(a2.asXml()); 

    a1.click(); 
    a2.click(); 
    */ 
    /*

您的情況適用於最新版本/快照。

<a href="play.php?choose=2">

try (WebClient webClient = new WebClient()) { 
    HtmlPage page = webClient.getPage("http://localhost:8080"); 
    HtmlAnchor a1 = page.getAnchorByHref("play.php?choose=2"); 
    System.out.println(a1.asXml()); 
    HtmlAnchor a2 = page.getFirstByXPath("//a[@href='play.php?choose=2']"); 
    System.out.println(a2.asXml());
