title: XPath: How do you do a lowercase call in xpath
body: <p>I'm using Firefox's XPath-checker and can't get the syntax right. I have a link:</p>
  
  <pre><code>&lt;a&gt;LinkName&lt;/a&gt;
  </code></pre>
  
  <p>and I try doing:</p>
  
  <pre><code>//a[lower-case(child::text())='linkname']
  </code></pre>
  
  <p>but I have a syntax error. What am I doing wrong?</p>
  
  <p>Thanks</p>
