Basic XML to nested Array

Ruby
1

Hey,

I’ve been having some trouble getting to grips with the various XML
libraries, I just want to put together a ruby script that will convert a
basic XML file into a nested array then just output that array to the
console.

The XML looks like this:


1018.550659
558.138367
102.505821


1013.557495
560.874878
107.041840


1008.563049
563.611267
111.577576




1030.809204
551.722961
86.581741


1027.500854
553.190613
95.061058

and I want to make it this:
[[[1018.550659],[558.138367],[102.505821]],[[1013.557495],[560.874878],[107.041840]],[[1008.563049],[563.611267],[111.577576]]],[[[1030.809204],[551.722961],[86.581741]],[[1027.500854],[553.190613],[95.061058]]]

Anyone know the best way to go about this?

Thanks very much!

Your xml file is missing the root element.
If your xml file is ‘a.xml’, you can do something like this:

require ‘rexml/document’
doc = REXML::Document.new(“”+File.read(“a.xml”)+“”)
res = doc.elements.to_a(“//”).map{|e1|
e1.elements.to_a.map{|e2|e2.elements.to_a.map{|e3|e3.text}}
}
p res

Yeah the program outputting this stuff doesn’t add a root element so
great tip there, it worked perfectly thanks Heesob!

require ‘rexml/document’
doc = REXML::Document.new(""+File.read(“a.xml”)+"")
res = doc.elements.to_a("//").map{|e1|
e1.elements.to_a.map{|e2|e2.elements.to_a.map{|e3|e3.text}}
}
p res
