XML is just a way to store and transfer data. It is used for a lot of things from storing program configuration to transfering database query results to creating office documents. There is no "standard" way of converting XML into PDF or HTML. There are probably renderers out there that will do syntax highlighting on XML files, but I guess that is not what you want. There is also a technology called XSLT, that is specifically created to translate an XML document into something else. If your goal is to publish documents in different formats using XML you should look at docbook http://www.docbook.org/ docbook is a formal XML/SGML document format complete with conversion scripts, stylesheets etc. that allows to write an article or a book or some other form of document in XML and automatically convert it into HTML or postscript or something else. To get a more complete understanding of what XML is and what it is used for, check http://en.wikipedia.org/wiki/XML
