IXPathResult

IXPathResult interface

The XPathResult interface represents the result of the evaluation of an XPath 1.0 expression within the context of a particular node. Since evaluation of an XPath expression can result in various result types, this object makes it possible to discover and manipulate the type and value of the result.
