There are multiple implementation of StAX API and you can chose an implementation that best suites your need: from Reference Implementation (RI) that is based on XPP under Apache License to GPL-ed implementation:

Reference Implementation (RI) at codehaus based on XPP3/MXP1 under Apache 2.0 License
WoodSToX is a fast Open Source XML-processor written in Java under dual Apache 2.0 and LGPL License.

XmlPull API Implementations

There are multiple implementation of XmlPull API and you can chose an implementation that best suites your need: from a very small implementation that is handheld devices friendly (KXML2 that is J2ME compatible) through optimized for performance but not necessarily implementing fully XML 1.0 (XPP3) to version that uses Xerces 2 as engine (and provides fully compliance with XML 1.0 but it is not small).

XNI 2 XmlPull based on Xerces 2 and is an implementation of XmlPull API that is providing both validating and non-validating XML 1.0 parser
XPP3/MXP1 implementation that focuses on performance and ease of use
KXML2 small J2ME optimized implementation that has very small memory footprint

Short summary of available implementations:

Additional remarks	implementation of XmlPull API based on Xerces 2 XNI is that concentrates on fully XML 1.0 compatibility currently on beta stage (needs more testing), currently available only from CVS	development beta version (though soon should be stable) that is based on new MXP1 engine (rebuilt XPP2), very good performance especially for small input files, JAR file size <23K (just parser without serializer)	stable version, focused on minimum size and designed to run great in J2ME environments, further modules for KXML are under development (such as WBXML), kxml-min jar (just the parser and interface) size 9.1K (just parser without serializer)
