A Java implementation of XProc: An XML Pipeline Language
This project is now abandoned in favour of MorganaXProc-III which implements XProc 3.0: https://sourceforge.net/projects/morganaxproc-iiise/
MorganaXProc is a full implementation of XProc: An XML Pipeline Language (W3C Recommendation 11 May 2010) written in Java, supporting all required and optional steps, the steps proposed on EXProc.org and also the document templating steps "p:in-scope-names" and "p:template".
XPath 2.0 or XPath 3.0 is used as expression language.

The main objective of the EXIP project is to provide a C library for parsing and serialization of Efficient XML Interchange (EXI) Format streams. The focus is portability and efficiency for embedded systems development.
FUGE is a lightweight GUI library, intended to be used primarily in games and tools for game development. Supports graphics renderer adaptation, real-time layout editing, XML serialization, color schemes. Documentation contain tutorials with examples. Available on MS Windows and Linux.
FFJUXS Free Java Universal XML Serializer: The aim of this project is to create a serializer that supports anything the standard Java Serializion supports (not just JavaBeans) - and more - using the XML file format and giving many options.
The JPList project provides a Java library for parsing and building ASCII PList streams to and from Java objects, similar to what JDOM does for XML. PLists provide a more compact and equally rich alternative to XML as a data serialization mechanism.
