http://blog.innovimax.fr/index.php/2011/08/11/38-xproc-quine You may have heard of the Quicksort implementation in XProc<http://en.literateprograms.org/Quicksort_(XProc)> of the famous algorithm <http://en.wikipedia.org/wiki/Quicksort> in XProc<http://w3.org/TR/xproc> Here comes now the Quine <http://en.wikipedia.org/wiki/Quine_(computing)>, * i.e* a computer program which takes no input and produces a copy of its own source code as its only output. <?xml version="1.0" encoding="UTF-8"?> <p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="1.0"> <p:documentation> <p>(c) Innovimax 2011 - The first XProc Quine</p> </p:documentation> <p:output port="result"/> <p:identity> <p:input port="source"> <p:inline> <p:declare-step version="1.0"> <p:documentation> <p>(c) Innovimax 2011 - The first XProc Quine</p> </p:documentation> <p:output port="result"/> <p:identity> <p:input port="source"> <p:inline/> </p:input> </p:identity> <p:insert match="p:inline" position="first-child"> <p:input port="source"/> <p:input port="insertion"/> </p:insert> </p:declare-step> </p:inline> </p:input> </p:identity> <p:insert match="p:inline" position="first-child"> <p:input port="source"/> <p:input port="insertion"/> </p:insert> </p:declare-step> It works in any of the many implementations of XProc<http://xproc.org/implementations/>. If you run for GPL <http://en.wikipedia.org/wiki/GNU_General_Public_License>, go look atQuiXProc <http://code.google.com/p/quixproc> Xmlizer
