Hi Jason,
AFAIK, XPath.selectNodes() returns an Array.
<snippet from the docs>
/**
10 * selectNodes
11 *
12 * returns an array of nodes that match the given XPath
13 * expression using the the XMLNode (context) as the
14 * starting context for the expression.
15 *
16 * This is the description
17 * @param (XMLNode)context
18 * @param (String)XPath expression
19 * @return (Array) matching nodes
20 */
21 static function selectNodes(context,path:String):Array{
22 return XPathParser.parseQuery(context,path)
23 }

</snippet from the docs>
HTH,
