Parsing XML from commandline
by Mark Rogers 07 Nov '13

07 Nov '13

Given the following: <?xml version="1.0" encoding="utf-8"?> <Project> <Network> <Unit> <UnitType>Type1</UnitType> <SerialNumber>123456</SerialNumber> </Unit> <Unit> <UnitType>Type2</UnitType> <SerialNumber>abcdef</SerialNumber> </Unit> [... snip...] </Network> </Project> .. I need to extract all the serial numbers where UnitType is "Type2". I have never managed to get my head around XPath etc, and all the examples I find seem either too general or too complex for me to make much progress. I always end up writing some code that parses it as text which is a massive cop out. How best can I do this correctly using XML tools, and which tools should I use?

Uninstall problem
by Bev Nicolson 05 Nov '13

05 Nov '13

Somehow (and clearly it wasn't sensible) I've got Calibre on this machine but it doesn't show as installed in Synaptic so I can't remove it. What can I do? I get permission denied if I try to delete it. Thoughts? Polite ones, if poss. Own silly fault etc. Bev.

xsane is sulking!
by Ted.Harding＠wlandres.net 04 Nov '13

04 Nov '13

Greetings All! I would welcome anything in the way of useful advice/tips about the following. I have a (rather old) Epson Perection 2400 scanner (USB). This has been working very well for years on an old desktop, using xsane. When xsane is started up on that machine there is an initial fairly lar egwindow which allows (if needed) configurations. I now want to use this scanner with a more recent laptop which is running a 2011 version of Debian. It seems that xsane is correctly installed. Now: With the scanner powered on, I plug its USB lead into the laptop. After a second or two, the scanner makes the usual "initialisation" noises (scanner arm shifting up & down). So something is OK, at least at the scanner end. I then invoke xsane at the command line. Up comes a little window (not the big window like on the other machine) with a message "scanning for devices". Then the window says: "failed to open device 'v4l:/dev/video0" and the only option remaining is to close the window, at which point the instance of xsane closes. I have no idea why it should be looking for a *video* device! I can find no work-round for this. It might be that the laptop had not detected the scanner (how can I tell?). There is no icon for it on the GNOME desktop (but that didn't happen either when I connected my USB printer; and that works perfectly well). Any suggestions gratefully received! Best wishes to all, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 02-Nov-2013 Time: 21:25:23 This message was sent by XFMail -------------------------------------------------

Best distro for XP users
by Mark Rogers 04 Nov '13

04 Nov '13

I'm being asked quite frequently now for Linux options to replace XP. What would people here pick? Hardware will generally be pretty old so good support for older hardware is important. I note that current Ubuntu versions only get updates for 9 months from release (ie 3 months after they cease to be current) which is fine as long as the next version updates smoothly, but that would depend on continued support for the older hardware, and I know from experience that updates aren't always smooth (typically graphics issues as an older card loses support). I can go with the LTS version of-course, would that be better? Mint follows the same release cycle but doesn't (AFAIK?) provide upgrades. There's no point replacing XP because it's reached EOL with a Linux distro that will go EOL a few months later unless updates are pretty much guaranteed to work without my assistance. (I use Kubuntu in general on my own boxes and would prefer to stick with .deb -based systems, which rules out Fedora/OpenSUSE/etc.) And then there's the choice of desktop - probably something less memory hungry than KDE - or do I look at MATE, Cinnamon, etc with which I have no experience? I'm not great at Linux advocacy because I don't have the confidence in my ability to pick the right option for friends and family who "want" XP... -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
