# If CCR is set to a string containing a valid CCR and
# XSD is a string containing the CCR XSD, this will
# print out the medications in the CCR:
require 'rubygems'
# sudo gem install libxml-ruby
require 'xml/libxml'
class XSDRead
MEDS = '//ContinuityOfCareRecord/Body/Medications/Medication'
def read
doc = XML::Parser.string(CCR).parse
xsd = XML::Schema.from_string(XSD)
doc.validate_schema(xsd)
doc.find(MEDS).each do |node|
str = node.content
puts "#{str}" unless str.empty?
end
end
