The class provides an implementation of XPathEvaluator according
to the DOM L3 XPath Specification, Working Group Note 26 February 2004.
See also the Document Object Model (DOM) Level 3 XPath Specification.
The evaluation of XPath expressions is provided by
XPathEvaluator
, which will provide evaluation of XPath 1.0
expressions with no specialized extension functions or variables. It is
expected that the
XPathEvaluator
interface will be
implemented on the same object which implements the
Document
interface in an implementation which supports the XPath DOM module.
XPathEvaluator
implementations may be available from other
sources that may provide support for special extension functions or
variables which are not defined in this specification.
