<p>Converts between an XML string and its JavaScript object representation, in either direction.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">object | string</span></dt>
<dd>A JavaScript object or XML string.</dd>

<h3>Outputs</h3>
<dl class="message-properties">

<dd>
<ul>
<li>If the input is a string it tries to parse it as XML and creates a JavaScript object.</li>
<li>If the input is a JavaScript object it tries to build an XML string.</li>
</ul>

<dt class="optional">options <span class="property-type">object</span></dt>
<dd>This optional property can be used to pass in any of the options supported by the underlying
library used to convert to and from XML. See <a href="https://github.com/Leonidas-from-XIV/node-xml2js/blob/master/README.md#options" target="_blank">the xml2js docs</a>
for more information.</dd>
</dl>
<h3>Details</h3>
<p>When converting between XML and an object, any XML attributes are added as a property named <code>$</code> by default.
Any text content is added as a property named <code>_</code>. These property names can be specified in the node configuration.</p>
<p>For example, the following XML will be converted as shown:</p>
<pre>&lt;p class="tag"&gt;Hello World&lt;/p&gt;</pre>
<pre>{
"p": {
"$": {
"class": "tag"
},
"_": "Hello World"
}
}</pre>
