title: Odoo - Find and remove <p> tag
body: <p>I want to remove the <code>&lt;p&gt;</code> element:</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;record model=&quot;ir.ui.view&quot; id=&quot;helpdesk_support_form_view&quot;&gt;
    &lt;field name=&quot;name&quot;&gt;Helpdesk form&lt;/field&gt;
    &lt;field name=&quot;model&quot;&gt;helpdesk.support&lt;/field&gt;
    &lt;field name=&quot;arch&quot; type=&quot;xml&quot;&gt;
      &lt;form&gt;
        &lt;sheet&gt;
          &lt;group&gt;
            &lt;group&gt;
              &lt;field name=&quot;total_spend_hours&quot; widget=&quot;float_time&quot; attrs=&quot;{'readonly': [('stage_type', '=', 'closed')]}&quot;/&gt;
      
              &lt;p style=&quot;color:grey;&quot; colspan=&quot;3&quot;&gt;Some text here&lt;/p&gt;
      
            &lt;/group&gt;
          &lt;/group&gt;  
        &lt;/sheet&gt;
      &lt;/form&gt;
    &lt;/field&gt;
  &lt;/record&gt;
  </code></pre>
  <p>How can I achieve this?</p>
  <p>I inherited the view and tried to add:</p>
  <pre class="lang-xml prettyprint-override"><code>  &lt;xpath expr=&quot;//p&quot; position=&quot;replace&quot;&gt;
      &lt;span&gt;&lt;/span&gt;
    &lt;/xpath&gt;
  </code></pre>
  <p>But I get this error:</p>
  <pre class="lang-sh prettyprint-override"><code>File &quot;src/lxml/lxml.etree.pyx&quot;, line 3501, in lxml.etree._Validator.assert_ (src/lxml/lxml.etree.c:184715)
  AssertionError: Element odoo has extra content: data, line 2
  </code></pre>
  <p>Thank you</p>
