The gold standard Stax XML "pull" API ( implementation.

Since version 4.0, Woodstox also implements SAX API for event-based XML processing.

Most if not all popular Java XML web service frameworks use either Stax or SAX API for XML processing: this means that Woodstox can be used with the most popular Java frameworks.

For longer overview, here are some options for more reading:

But in general usage follows standard Stax or SAX API usage.

The most common way is to use Maven (or Ivy) to access it from Maven Central repository. Coordinates for this are:

  • Group id: com.fasterxml.woodstox
  • Artifact id: woodstox-core
  • Latest published version: 6.6.1 (2024-02-26)

Note that Maven id has changed since Woodstox 4.x but API is still compatible (despite nominal major version upgrade -- major version upgrades in this case were only due to package coordinate changes)


Woodstox 5 and above require Java 6 (JDK 1.6); as well as Stax API that is included in JDK. The only other mandatory dependency is Stax2 API, extended API implemented by Woodstox and some other Stax implementations (like Aalto.

Optional dependency is Multi-Schema Validator (MSV) that is needed if using XML Schema or RelaxNG validation functionality

Most configuration is handled using standard Stax mechanism, property access via

  • XMLInputFactory.setProperty(propertyName, value) for configuring XML reading aspects
  • XMLOutputFactory.setProperty(propertyName, value) for configuring XML writing aspects

Names of properties available, including standard Stax 1.x ones, are documented in a series of blog posts:
