<p>Set, change, delete or move properties of a message, flow context or global context.</p>
|
|
<p>The node can specify multiple rules that will be applied in turn.</p>
|
|
<h3>Options</h3>
|
|
<p>The available operations are:</p>
|
|
<dl class="message-properties">
|
|
<dt>Set</dt>
|
|
<dd>set a property. The value can be a variety of different types, or
|
|
can be taken from an existing message or context property.</dd>
|
|
<dt>Change</dt>
|
|
<dd>search & replace parts of the property. If regular expressions
|
|
are enabled, the "replace with" property can include capture groups, for
|
|
example <code>$1</code>. Replace will only change the type if there
|
|
is a complete match.</dd>
|
|
<dt>Delete</dt>
|
|
<dd>delete a property.</dd>
|
|
<dt>Move</dt>
|
|
<dd>move or rename a property.</dt>
|
|
</dl>
|
|
<h3>Details</h3>
|
|
<p>The "expression" option uses the <a href="http://jsonata.org/" target="_new">JSONata</a>
|
|
query and expression language. You can paste your data into <a href="http://try.jsonata.org/" target="_new">this site it</a>
|
|
to experiment and then use the expression back here.</p>
