net.sf.saxon.sxpath.XPathEvaluator
This class provide a native Saxon API for free-standing evaluation of XPath expressions. Unlike the JAXP API offered by {@link net.sf.saxon.xpath.XPathEvaluator} it exposes Saxon classes and interfacesand thus provides a more strongly-typed interface with greater control over the detailed behaviour. @author Michael H.

net.sf.saxon.xpath.XPathEvaluator

XPathEvaluator provides a simple API for standalone XPath processing (that is, executing XPath expressions in the absence of an XSLT stylesheet). It is an implementation of the JAXP 1.3 XPath interface, with additional methods provided (a) for backwards compatibility (b) to give extra control over the XPath evaluation, and (c) to support XPath 2.0.

It is intended to evolve this so that it only supports the JAXP style of operation. Some of the methods are therefore marked as deprecated in this release, and will be dropped in a future release.

For an alternative XPath API, offering more direct access to Saxon capabilities, see {@link net.sf.saxon.sxpath.XPathEvaluator}.

Note that the XPathEvaluator links to a Saxon {@link Configuration}object. By default a new Configuration is created automatically. In many applications, however, it is desirable to share a configuration. The default configuration is not schema aware. All source documents used by XPath expressions under this evaluator must themselves be built using the Configuration used by this evaluator.
