循环，直到然后单击元素

Question

我想单击查看更多按钮，直到看到某个链接文本元素，然后单击该链接文本。我将如何创建该循环？我尝试了其他方法，但仍然无法正确完成：

WebElement viewmorebutton = wdriver.findElement(By.xpath(".//*[@id='content']/input"));
                    while(checkButton(viewmorebutton)){
                        wdriver.findElement(By.id(TransationListingWeb.getView_more_transactions_button_id())).click();
                        if( wdriver.findElement(By.linkText("LOTTO (20-03-2019)")).isDisplayed()){
                            wdriver.findElement(By.linkText("LOTTO (20-03-2019)")).click();

                        }else
                            wdriver.findElement(By.id(TransationListingWeb.getView_more_transactions_button_id())).click();
                }
