import  com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;import  com.gargoylesoftware.htmlunit.WebClient;import  com.gargoylesoftware.htmlunit.html.HtmlPage;     public   static   void  getHomeTile()  throws  FailingHttpStatusCodeException, MalformedURLException, IOException{         final  WebClient webClient  =   new  WebClient();         final  HtmlPage htmlPage  =  webClient.getPage( " http://www.oschina.net " );         System.out.println(htmlPage.getTitleText());         System.out.println(htmlPage.getTextContent());    }

示例二：获取一个特定的浏览器版本

public   void  homePage_Firefox()  throws  Exception {     final  WebClient webClient  =   new  WebClient(BrowserVersion.FIREFOX_2);     final  HtmlPage page  =  webClient.getPage( " http://htmlunit.sourceforge.net " );     assertEquals( " HtmlUnit - Welcome to HtmlUnit " , page.getTitleText());}

示例三：获取特定ID的DIV或者锚链接

public   void  getElements()  throws  Exception {     final  WebClient webClient  =   new  WebClient();     final  HtmlPage page  =  webClient.getPage( " http://some_url " );     final  HtmlDivision div  =  page.getHtmlElementById( " some_div_id " );     final  HtmlAnchor anchor  =  page.getAnchorByName( " anchor_name " );}

实例四：模拟页面提交一个form

public   void  submittingForm()  throws  Exception {     final  WebClient webClient  =   new  WebClient();     //  Get the first page      final  HtmlPage page1  =  webClient.getPage( " http://some_url " );     //  Get the form that we are dealing with and within that form,      //  find the submit button and the field that we want to change.      final  HtmlForm form  =  page1.getFormByName( " myform " );     final  HtmlSubmitInput button  =  form.getInputByName( " submitbutton " );     final  HtmlTextInput textField  =  form.getInputByName( " userid " );     //  Change the value of the text field      textField.setValueAttribute( " root " );     //  Now submit the form by clicking the button and get back the second page.      final  HtmlPage page2  =  button.click();}
