ColdFusion MX: Added this function.

The following example tests whether an XML document object, its root element, and a child element are XML root elements:

<!--- Create an XML document object --->
<cfxml variable="xmlobject">
<?xml version="1.0" encoding="UTF-8"?>
<order id="4323251">
   <customer firstname="Philip" lastname="Cramer" accountNum="21"/>
   <items>
      <item id="43">
         <quantity>1</quantity>
         <unitprice>15.95</unitprice>
      </item>
   </items>
</order>
</cfxml>

<!--- Test objects to see if they are XML root elements --->
<cfoutput>
<h3>Are the following the XML Root?</h3>
xmlobject: #IsXmlRoot(xmlobject)#<br>
xmlobject.order: #IsXmlRoot(xmlobject.order)#<br>
<!--- The order element id attribute --->
xmlobject.order.XmlAttributes.id: 
   #IsXmlRoot(xmlobject.order.XmlAttributes.id)#<br>
</cfoutput>
