## Package net.sf.saxon.sxpath

This package provides an alternative API for executing XPath expressions directly from a Java application: unlike the API in package `net.sf.saxon.xpath`, these interfaces are not dependent on JAXP 1.3.

See:
Description

Interface Summary
XPathStaticContext | This interface defines methods that must be provided when Saxon's free-standing XPath API is used.

Class Summary
AbstractStaticContext | An abstract and configurable implementation of the StaticContext interface, which defines the static context of an XPath expression.
DedicatedStaticContext | This implementation of the XPath static context is mainly used when XPath expressions are hosted in other Saxon processing contexts, for example in xsl:evaluate, or in XSD assertions
IndependentContext | An IndependentContext provides a context for parsing an XPath expression appearing in a context other than a stylesheet.
SimpleContainer | A simple container for standalone XPath expressions
XPathDynamicContext | This object represents the dynamic XPath execution context for use in the free-standing Saxon XPath API.
XPathEvaluator | This class provides a native Saxon API for free-standing evaluation of XPath expressions.
XPathExpression | This class is a representation of an XPath Expression for use with the `XPathEvaluator` class.
XPathVariable | An object representing an XPath variable for use in the standalone XPath API.

## Package net.sf.saxon.sxpath Description

This package provides an alternative API for executing XPath expressions directly from a Java application: unlike the API in package `net.sf.saxon.xpath`, these interfaces are not dependent on JAXP 1.3. The API can be used either in a free-standing Java application (that is, where there is no XSLT stylesheet), or it can be used from within Java extension functions called from XPath expressions within a stylesheet.

The preferred API for executing XPath expressions in Saxon is the `s9api` package. This package is older, and provides a lower-level interface that offers access to more internal details, but is not so convenient to use.
