title: How can I escape double quotes in XML attributes values?
body: <p>From the following trials</p>
  
  <pre><code>&lt;tag attr="\""&gt;
  &lt;tag attr="&lt;![CDATA["]]&gt;"&gt;
  &lt;tag attr='"'&gt;
  </code></pre>
  
  <p>Only the last one works for an XML parser that I'm using here.
  Is there an alternative?</p>
