<p>Set, change or delete properties of a message.</p>

<p>The node can specify multiple rules that will be applied to the message in turn.</p>
|

<p>The available operations are:</p>
|
|
<ul>
|
|
<li><b>Set</b> - set a property. The <b>to</b> property can either be a string value, or reference
|
|
another message property by name, for example: <code>msg.topic</code>.</li>
|
|
<li><b>Change</b> - search & replace parts of the property. If regular expressions
|
|
are enabled, the <b>replace with</b> property can include capture groups, for example <code>$1</code></li>
|
|
<li><b>Delete</b> - delete a property.</li>
