Parameters

xpath

A string representing an XPath expression.

resolver

The System.Xml.IXmlNamespaceResolver object used to resolve namespace prefixes in the XPath query.

Returns

An System.Xml.XPath.XPathNavigator object that contains the first matching node for the XPath query specified; otherwise null if there are no query results.

Remarks

The XPathNavigator.SelectSingleNode(string, System.Xml.IXmlNamespaceResolver) method selects the first node that matches the XPath query specified. The XPathNavigator.SelectSingleNode(string, System.Xml.IXmlNamespaceResolver) method uses the System.Xml.IXmlNamespaceResolver object to resolve namespace prefixes.

Note:

In XPath all namespaces must be prefixed in a query. If an XML document uses a default namespace, you must still add a namespace prefix to the System.Xml.IXmlNamespaceResolver object.
