Visual Basic (Declaration)

There is some performance penalty for using these methods. Using LINQ to XML queries yields better performance.

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.

System..::.Object
  System.Xml.XPath..::.Extensions

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
