title: How to match element by text ignoring case?
body: <p>For example, I have an element</p>
  
  <pre><code>&lt;div&gt;TestMessage&lt;div&gt;
  </code></pre>
  
  <p>How do I get this element by 'testmessage' text?</p>
  
  <p>Next options don't work:</p>
  
  <pre><code>//div[contains(., 'testmessage')]
  //div[matches(text(),'testmessage','i')]
  //div[lower-case(text())='testmessage'] 
  //div[lower-case(.)='testmessage']
  </code></pre>
