Overview

s9api Interface
Package	Description
net.sf.saxon.s9api	This package provides Saxon's preferred Java API for XSLT, XQuery, XPath, and XML Schema processing.

Other Interfaces
Package	Description
net.sf.saxon	This package provides the core classes of the SAXON XSLT library.
net.sf.saxon.lib	This package collects together interfaces intended for user applications to implement in order to customize Saxon's behavior, default implementations of these interfaces, and classes containing constants that are used in public Saxon interfaces.
net.sf.saxon.om	This package defines the interface to the Saxon tree structure.
net.sf.saxon.query	This package provides a relatively low-level API for executing XQuery queries directly from a Java application.
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.
net.sf.saxon.type	This package contains classes that implement the XPath 2.0 type system.
net.sf.saxon.value	This package provides classes representing XPath values (that is, the results of an expression).
net.sf.saxon.xpath	This package is Saxon's implementation of the JAXP API designed for executing XPath 1.0 expressions directly from a Java application.

net.sf.saxon.option.axiom	This package contains classes that interface Saxon to the Apache AXIOM tree model.
net.sf.saxon.option.dom4j	This package provides glue classes that enable Saxon to process a source document supplied as a DOM4J tree (see https://dom4j.github.io).
net.sf.saxon.option.exslt	This package provides implementations of the functions defined in EXSLT.
net.sf.saxon.option.jdom	This package provides glue classes that enable Saxon to process a source document supplied as a JDOM tree (see http://www.jdom.org).
net.sf.saxon.option.jdom2	This package contains classes that interface Saxon to the JDOM2 tree model.
net.sf.saxon.option.local	This package contains classes responsible for localizing the output of functions such as format-dateTime and format-integer into various languages.
net.sf.saxon.option.xom	This package provides glue classes that enable Saxon to process a source document supplied as a XOM tree (see http://www.cafeconleche.org/XOM).
net.sf.saxon.pattern	This package provides classes associated with XSLT pattern handling.
net.sf.saxon.pull	This package provides classes that interface Saxon to an XML parser that supplies data in the form of a stream of events.

net.sf.saxon.regex.charclass	This package contains Java classes used to represent character classes in regular expressions.
net.sf.saxon.resource	This package contains Java classes used to represent abstractions of resources of different kinds that can be retrieved as part of a collection (using the fn:collection function).
net.sf.saxon.serialize	This package contains code for serializing trees using the standard W3C-defined serialization methods (xml, html, text).
