Overview

The Java API for XML Processing (JAXP) enables applications to parse and transform XML documents using an API that is independent of a particular XML processor implementation. JAXP provides a pluggability layer over Parser and Transformer functionality. Using this software, application and tool developers can build fully-functional XML-enabled Java applications for e-commerce, application integration, and web publishing.

The JAXP expert group has wide industry participation with Sun Microsystems as the EG lead. An implementation of the JAXP 1.3 specification is included in the latest J2SE release, J2SE 5.

JAXP 1.3 adds many new features for fast and easy XML processing:

• A schema-independent validation framework, which decouples validation as a process independent from parsing.
• Schema can be compiled to an immutable memory representation of Grammar, which can validate different instances of an XML document, thereby improving the performance of XML processing.
• XPath language provides a simple, concise syntax for accessing individual parts of an XML document. JAXP 1.3 defines XPath APIs, which provide access to the XPath evaluation environment and expression results independent of the underlying data object model.
• JAXP 1.3 adds new datatypes that map to the following W3C XML Schema datatypes: xs:date, xs:dateTime, xs:duration, xs:gDay, xs:gMonth, xs:gMonthDay, xs:gYear, xs:gYearMonth, and xs:time.
• JAXP 1.3 also adds new datatypes that map to the following XQuery 1.0 and XPath 2.0 Data Model: xdt:dayTimeDuration and xdt:yearMonthDuration.
• JAXP 1.3 enables you to reset and reuse the same XML Parser and Transformer instance obtained from the factories to process multiple XML documents.
• JAXP 1.3 upgrades the following W3C standard: DOM L3, Core DOM L3, L/S, XML 1.1, and XInclude.

Conformance

The JAXP 1.3.1 release supports the following standards and specifications:

• JAXP 1.3
• SAX 2.0.2
• XML 1.1
• XML 1.0
• XInclude
• DOM Level 3 Core
• DOM Level 3 Load and Save
• W3C XML Schema
• XSLT 1.0
• XPath 1.0

Documentation

The documentation for this release consists of:

• Release notes
• Javadoc API documentation
• JAXP Samples
• JAXP FAQ

Samples

There are different types of samples, which show how to use the new functionality introduced as part of the JAXP 1.3 APIs, such as Schema Validation, XPath, etc. This distribution contains samples under the jaxp/samples directory. Going forward, new samples that demonstrate how to use the new APIs will be added. Please direct any questions you have about using the APIs to the XML Forums or Mailing lists.

XML Discussion Forums and Feedback

JAXP is a sub-project of the jwsdp project. Currently, we do not have a separate mailing list for JAXP but are reusing the jwsdp users mailing list. Please send questions about JAXP 1.3 to users@jswsdp.dev.java.net.

Please use the The Java Developer Connection (JDC) Forum on Java Technology & XML for questions about general problems with XML or XSLT.
