Basic XML to nested Array

[James Jhfghgfhgf]

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:
<vector>
<point>
<x>1018.550659</x>
<y>558.138367</y>
<z>102.505821</z>
</point>
<point>
<x>1013.557495</x>
<y>560.874878</y>
<z>107.041840</z>
</point>
<point>
<x>1008.563049</x>
<y>563.611267</y>
<z>111.577576</z>
</point>
</vector>
<vector>
<point>
<x>1030.809204</x>
<y>551.722961</y>
<z>86.581741</z>
</point>
<point>
<x>1027.500854</x>
<y>553.190613</y>
<z>95.061058</z>
</point>
</vector>

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 =3D REXML:ocument.new("<root>"+File.read("a.xml")+"</root>")
res =3D 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!
