I have a Mule flow with a XML payload like:

```
<?xml version="1.0" encoding="utf-16"?>
<root type="1" name="blah">
  <blablah value="10" desc="Material" />
</root>

```

I want to rename the "root" node and tried using the xml-to-dom-transformer and expression component. However, I have no idea how to do that.I tried something like this that did not help:

```
    <expression-component><![CDATA[
      node = message.payload.getRootElement();
      node.renameNode = 'peo';
    ]]></expression-component>

```
