How do I use this? This example throws an error. I'm trying to test for the existence of a node.

<cfscript>
myXMLDoc = XmlNew();
myXMLDoc.xmlRoot = XmlElemNew(myXMLDoc,"people");
myXMLDoc.people.XmlText = "bla bla bla";
myXMLDoc.people.XmlChildren[1] = XmlElemNew(myXMLDoc,"name");
myXMLDoc.people.XmlChildren[1].XmlAttributes.id = 1;
myXMLDoc.people.XmlChildren[1].XmlAttributes.sexo = "M";
myXMLDoc.people.XmlChildren[1].XmlText = "Marcello";
myXMLDoc.people.XmlChildren[2] = XmlElemNew(myXMLDoc,"name");
myXMLDoc.people.XmlChildren[2].XmlAttributes.id = 2;
myXMLDoc.people.XmlChildren[2].XmlAttributes.sexo = "F";
myXMLDoc.people.XmlChildren[2].XmlText = "Maria";
</cfscript>

<cfoutput>
IsXmlRoot(myXMLDoc.people): #IsXmlRoot(myXMLDoc.people)#<br>
IsXmlElem(myXMLDoc.people): #IsXmlElem(myXMLDoc.people)#<br>
IsXmlElem(myXMLDoc.people.name): #IsXmlElem(myXMLDoc.people.name)#<br>
IsXmlElem(myXMLDoc.people.blah): #IsXmlElem(myXMLDoc.people.blah)# - Shouldn't this return no? Instead of an error?<br>
</cfoutput>

What about testing for the existence of an XMLAttribute?

To test for the existance of an XML attribute, you can use the StructKeyExists function, since an XML node is a structure. Pass in the attribute name for the "key" parameter.
