title: how to change ionic app version using xmlstarlet?
body: <p>I'm trying to change my ionic app version when i add a new release to my git repo. In order to achieve this I executing <code>xmlstarlet ed -L -u 'widget\@version' -v '&lt;tag value&gt;' config.xml</code> but the output came with nothing changed. I have already tried the xpath expression and it find the node.
  this is 'config.xml' file:</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot;?&gt;
  &lt;widget xmlns=&quot;http://www.w3.org/ns/widgets&quot; xmlns:cdv=&quot;http://cordova.apache.org/ns/1.0&quot; id=&quot;io.ionic.my_app&quot; version=&quot;1.0.3&quot;&gt;
  ...
  &lt;/widget&gt;
  
  </code></pre>
  <p>If I remove the properties <code>xmlns</code> and <code>xmlns:cdv</code> it works, why those properties affects how <code>xmlstarlet</code> works and how can I fix this?</p>
