class Nokogiri::XML::RelaxNG
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.
NOTE: RelaxNG
input is always treated as TRUSTED documents, meaning that they will cause the underlying parsing libraries to access network resources. This is counter to Nokogiri’s “untrusted by default” security policy, but is a limitation of the underlying libraries.
