XPathDocument
This class is a concrete implementation of IXPathNavigable for
creating an XPathNavigator that knows how to scan through an
XML document. There are overloaded forms of the constructor designed to pull an
XML document from various sources—a System.IO.Stream, a string,
a System.IO.TextReader (which presumably is pulling from some
other valid data source), or a System.Xml.XmlReader. Note that
if the XmlReader is
currently positioned on top of a particular
node within a document, the constructed XPathDocument instance
is only valid for that element and its children. This allows partial
XPath scans of a given document.
This class serves no other purpose than as a factory for producing XPathNavigator instances.
