Class Nokogiri::XML::RelaxNG inherits from Nokogiri::XML::Schema
Nokogiri::XML::RelaxNG is used for validating XML against a RelaxNG schema.
Synopsis
Validate an XML document against a RelaxNG schema. Loop over the errors that are returned and print them out:
schema = Nokogiri::XML::RelaxNG(File.open(ADDRESS_SCHEMA_FILE)) doc = Nokogiri::XML(File.open(ADDRESS_XML_FILE)) schema.validate(doc).each do |error| puts error.message end
The list of errors are Nokogiri::XML::SyntaxError objects.
