Please disregard the previous post.  I figured out how to load the
files, but it does not appear to be reading correctly.

Using-
fname = File.open("C:/Users/Kyle/Desktop/CSUF/Research Winter
11/IFXCML/automation trials/one.xml")
$doc = Nokogiri::XML(fname)
reference = $doc.css(" IfcCartesianPoint Coordinates
IfcLengthMeasure").first

This produce and output of nil when it should be "117.4" correct?  What
is going wrong here?
