Hi, In my job I now need to transfer data between application using XML. As an absolute beginner in this field I'm asking you the very very basic of XML. As far as I know having leafed through debian documentation XML as a tagged language is a subset of SGML therefore: 1) What deb packages should I install to build and view XML documents? 2) Where can I find documentation both on the packages themselves and, above all, on XML? Ciao Vittorio
