The tutorials web page now has the latest set of tutorial exercises. For these you get to work directly with XML and XPath, using the
xmllint command-line tool.
xmllint tool is installed on DICE machines, and I recommend that you check you are able to use it there.
It’s also available for other platforms as part of the Gnome
libxml2 toolkit, which is “known to be very portable, the library should build and work without serious troubles on a variety of systems (Linux, Unix, Windows, CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks, …)”. If it’s already on your favourite machine and operating system, or you are able to install it there, wonderful; if it isn’t and you can’t, then use the version on DICE.
