For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |
Reading in XML in Ruby with xmlsimple
The xmlsimple Ruby gem allows you to load in a file (or IO handle object or string) of XML as a multidimensional collection - hashes of arrays of hashes. There's a sample program here which includes this code to load the data from after __END__:
require 'xmlsimple'
info = XmlSimple.xml_in(DATA)
If I now the structure of what I'm getting, I can then access elements directly, for example:
p info["access"][0]["where"][0]
and if I don't know what the structure is, I can use Ruby to explore it. The source code at the link above contains a complete recursive piece of code for displaying a Hash that contains hashes, arrays and printable values to get you started!
There's an example using the alternative (standard) rexml library - [here]. (written 2016-05-18, updated 2016-05-19)
