JAXP XPath API
Saxon implements the JAXP 1.3 API for executing XPath expressions as defined in package
java.xml.xpath, which is a standard part of the Java class library since
JDK 1.5. Three sample applications using this API are available: they are called
ApplyXPathJAXP.java, and can be found in the
directory after downloading the
To run the
XPathExample.java application, see the instructions in Shakespeare XPath Sample
XPathExampleSA.java application demonstrates use of schema-aware XPath. It
is designed to be used with the files
ApplyXPathJAXP.java application is an enhanced version of the class of the
same name issued as a sample application in the JAXP 1.3 distribution. It has been enhanced
to show the use of more advanced features, such as the ability to bind namespaces,
variables, and functions, and also to demonstrate use of the XPath API with different
The XPath API in Saxon predates the introduction of the JAXP 1.3 XPath API, so it contains some facilities that are obsolescent (but most of the deprecated features were removed with effect from Saxon 9.6). However, there are also differences caused by the fact that Saxon supports XPath 2.0 (and higher), with its richer data model, whereas JAXP 1.3 operates only on XPath 1.0.
