How to insert text out of xml entries with etree.Element
<p>I built an xml file with lxml.etree, and this is the result:</p>

<pre><code>&lt;BigData&gt;
  &lt;user&gt;
    &lt;enum&gt;
      &lt;tree&gt;sometext&lt;/tree&gt;
    &lt;/enum&gt;
   &lt;/user&gt;
&lt;/BigData&gt;
</code></pre>

<p>I am trying to put an entry and come up with this:</p>

<pre><code>&lt;BigData&gt;
  &lt;user&gt;**this_is_the_extra_text**
    &lt;enum&gt;
      &lt;tree&gt;sometext&lt;/tree&gt;
    &lt;/enum&gt;
   &lt;/user&gt;
&lt;/BigData&gt;
</code></pre>

<p>Any idea on how to do this?
if i use user = SubElement(user, BigData).text = 'this_is_the_extra_text', i get an error.
  Note: i just want plain text there, not a new xml entry.</p>

<p>Thanks!</p>
