title: check if element is present
body: <p>I use selenium web-driver in Eclipse.I need to check if table is displayed on page. I use such code:</p>
  
  <pre><code>try {
      Assert.assertTrue(driver.findElement(By.xpath(".//*[@id='flexibleTable']")).isDisplayed());
  } catch (AssertionError e) {
      System.err.println("overview not found: " + e.getMessage());
  }
  </code></pre>
  
  <p>Also block if</p>
  
  <pre><code>if (driver.findElement(By.xpath(".//*[@id='flexibleTable']")).isDisplayed()) {
      ...
  } else {
      ...
  }
  </code></pre>
  
  <p>But if such element is not found test is interrupted. How can I organize check so my test continue even if element is not on the page and block else will execute?</p>
  
  <p><strong>Edit</strong>
  Failure trace </p>
  
  <pre><code>org.openqa.selenium.NoSuchElementException: Unable to find element with xpath == .//*[@id='flexibleTable'] (WARNING: The server did not provide any stacktrace information)
