# == Synopsis
#
# Validate an XML document against a Schema. Loop over the errors that
# are returned and print them out:
#
# xsd = Nokogiri::XML::Schema(File.read(PO_SCHEMA_FILE))
# doc = Nokogiri::XML(File.read(PO_XML_FILE))
#
# xsd.validate(doc).each do |error|
# puts error.message
# end
#
# The list of errors are Nokogiri::XML::SyntaxError objects.
