QuiXProc is an open source implementation of XProc. The authors want QuiXProc to become a mainstream tool to process Structured and Unstructured Data, preserving high quality, high throughput, and low resources consumption.
XSLTXT is another compact form of expressing XSLT. It should increase the signal to noise ratio in XSLT stylesheets so that they are easier to write and hopefully easier to read.
xsltxt provides an alternative non-xml syntax for XSLT stylesheets that is easier to write, understand and maintain. The semantics of xsltxt are the same as XSLT written in XML, only the syntax is changed, and the standard
javax.xml.transform APIs are used to perform the actual transformations.
xmlsh is command line shell like the Unix shells but providing a familiar scripting environment specifically tailored for scripting XML processes.
The XSLTC is a Java-based tool for compiling XSLT stylesheets into lightweight and portable Java byte codes called translets.
Qexo is a partial implementation of the XML Query language. It achieves high performance because a query is compiled down to Java bytecodes using the Kawa framework.
