What I would like to achieve is to receive an email with the failures of my VPS. I tried to do that by downloading an rss feed XML file from my VPS provider which contains all the failures, down states etc. of their servers.

Once I downloaded it, I would like to parse it in order to see if my Virtual Host number is included in any of the entries of the XML file. If yes, I should receive an email containing the entire entry that contains my Virtual Host number (well, this is not a problem at all using sendmail). I have been unsuccessfully trying to use a simple and dirty wget and grep.

This is the file I would like to parse: http://www.hetzner-status.de/en.atom

    If you want to parse XML use an XML parser instead of grep. Libraries are available for every common language. Here's something to get you started: How do I parse XML in python?

    Are you really asking us to help you parse a file we can't see? Anyway, don't try to use regular expressions to parse XML files, it might wake up Tony.

  • @Marco: thank you for the suggestion, I'm very ignorant abouth python so I'd rather not using it, I would prefer a bash script. I hope I'm not being too choosy.

The utility you're looking for is xml2.

The xml2 command will convert an XML document into flat text. Using the URL you you gave as an example, here's a snippet of the conversion.

$ curl -sL http://www.hetzner-status.de/en.atom | xml2 | head
/feed/title=Hetzner Online AG - Status-Webseite
/feed/author/name=Hetzner Online AG

Each line is a key, which is an XML path, separated from its value by =. You should be able to get the rest using grep/cut or awk.

  • Thank you very much bahamat! I will check this out within tomorrow and I'll let you know how it went, but it looks exactly what I was looking for.
