XPath

The .NET Framework provides an API through which components can support XPath queries against underlying data stores. To use the XPath API, it’s necessary to understand the XPath language, a discussion of which is beyond the scope of this book. The W3C Recommendation "XML Path Language (XPath) Version 1.0," which is available at www.w3.org/TR/xpath, contains a complete definition of XPath.

This section discusses the .NET Framework classes provided to support XPath. Unless specifically stated otherwise, all XPath classes discussed in this section are members of the System.Xml.XPath namespace.
