The Parsimonious XML Shorthand Language (PXSL or ''pixel'') is a convenient shorthand for writing markup-heavy XML documents (ExtensibleMarkupLanguage). Created by TomMoertel. * http://community.moertel.com/pxsl/ * http://community.moertel.com/ss/space/pxsl There is a program written in HaskellLanguage which will translate from PXSL to XML. The idea is that PXSL is much easier to edit and so the user can maintain a file in PXSL which is translated when needed into XML. The web pages referenced here have some examples. Here is one for MathML (MathMl) taken from http://community.moertel.com/pxsl/ MathML example in XML <declare type="fn"> <ci> f </ci> <lambda> <bvar><ci> x </ci></bvar> <apply> <plus/> <apply> <power> <ci> x </ci> <cn> 2 </cn> </apply> <ci> x </ci> <cn> 3 </cn> </apply> </lambda> </declare> MathML example in PXSL declare -type=fn ci << f >> lambda bvar ci << x >> apply plus apply power ci << x >> cn << 2 >> ci << x >> cn << 3 >> ''And the obvious question is: How does PXSL handle namespaces? And how CDATA? Any examples for that?'' It has a structure for CDATA (see http://community.moertel.com/pxsl/ for more details). * XML: <![CDATA[ toast & jelly ]]> * PXSL: <{ toast & jelly }> It is also allowed to have XML in PXSL. There is a longer example of useage here: http://www.kuro5hin.org/story/2003/6/4/12434/75716 ----- How about :-) fn(f, lambda( bvar(x) x^2 + x + 3 ) ) ---- On WikiPedia (http://en.wikipedia.org/wiki/MathML#Content_MathML) is the example for ax^2 + bx + c in content MathMl <math> <apply> <plus/> <apply> <times/> <ci>a</ci> <apply> <power/> <ci>x</ci> <cn>2</cn> </apply> </apply> <apply> <times/> <ci>b</ci> <ci>x</ci> </apply> <ci>c</ci> </apply> </math> The following PXSL will generate the same XML: math apply plus apply times ci <<a>> apply power ci <<x>> cn <<2>> apply times ci <<b>> ci <<x>> ci <<c>> using the tool ''pxslcc'' which can be downloaded. ---- CategoryXml MarkupLanguage
