title: How to re-format an XML file in Phpstorm?
body: <p>I'm using Phpstorm and I have some XML file that is a single line only but contains a lot of (nested) elements. Just a common XML file:</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
  &lt;response&gt;&lt;status&gt;&lt;version&gt;4.2&lt;/version&gt;&lt;code&gt;0&lt;/code&gt;&lt;message&gt;Success&lt;/message&gt;&lt;/status&gt;&lt;songs&gt;&lt;song&gt;...
  </code></pre>
  <p>(<a href="https://gist.github.com/4426953" rel="nofollow noreferrer">gist of the full XML</a>).</p>
  <p>Having that file opened, I want to re-format it with indenting.</p>
  <p>I have tried using <em>Reformat Code...</em> (<kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>L</kbd>) but it didn't change anything. I also reviewed the XML Code-Style Settings, but I don't see anything standing in the way.</p>
  <p>Isn't it possible for Phpstorm to re-format an XML file to indent nested XML elements?</p>
  <p>Something into the direction like:</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
  &lt;response&gt;
    &lt;status&gt;
      &lt;version&gt;4.2&lt;/version&gt;
      &lt;code&gt;0&lt;/code&gt;
      &lt;message&gt;Success&lt;/message&gt;
    &lt;/status&gt;
    &lt;songs&gt;
      &lt;song&gt;
        ...
  </code></pre>
