	String^ expression

The XNode on which to evaluate the XPath expression.

Type: System::String^

A String that contains an XPath expression.

Return Value

Type: System::Object^

An object that can contain a bool, a double, a string, or an IEnumerable<T>.

If the collection is an enumeration of elements or attributes, you can use the Cast operator to get a collection of XElement or XAttribute.

Although the ordering of returned collections is not specified in the XML XPath Language 1.0 Recommendation, this extension method returns nodes in document order.

Note that nodes are returned in document order even when you use a reverse axis, such as preceding-sibling or ancestor-or-self.

The following example creates a small XML tree with an attribute, then uses the XPathEvaluate method to retrieve the attribute.

No code example is currently available or this language may not be supported.
