  <p>My xpath is :</p>
  
  <pre><code>  element =self.driver.find_element_by_xpath('//ul/li[text()="Portal"]')
  </code></pre>
  
  <p>I can get "RADIUS" clicked by xpath <code>'//ul/li[text()="RADIUS"]'</code>,but I get <code>"element not interactable"</code> by xpath <code>'//ul/li[text()="Portal"]'</code>.I don't know what's the different between element "RADIUS" and "Portal"</p>
