I'm following through the w3schools tutorial on xsd and xml validation and I'm trying to get one of the examples to validate. The problem seems to be in validating the attributes because if I strip them out, then it validates fine. I'm blindly following the tutorial but I can't see anything wrong with the xsd file, so dare I question if there is a bug?
Stripping out the w3schools example somewhat, if I was to take the following schema: <?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";> <!-- definition of attributes --> <xs:attribute name="orderid" type="xs:string"/> <xs:element name="shiporder"> <xs:complexType> <xs:attribute ref="orderid" use="required"/> </xs:complexType> </xs:element> </xs:schema> An xml file: <?xml version="1.0" encoding="ISO-8859-1"?> <shiporder orderid="889923" xmlns:xsi="http://www.w3.org/2001/ XMLSchema-instance" xsi:noNamespaceSchemaLocation="validator.xsd"> </shiporder> and a test script: require 'xml/libxml' include XML xsd_string = "" File.open('validator.xsd', 'r') do |f1| while line = f1.gets xsd_string += line end end doc = Document.file('test.xml') schema = XML::Schema.from_string( xsd_string ) print doc.validate(schema) Then I get the following errors >ruby test.rb false error -- found validity error: No declaration for attribute orderid of element shiporder error -- found validity error: No declaration for attribute noNamespaceSchemaLocation of element shiporder error -- found validity error: No declaration for attribute xmlns:xsi of element shiporder I would have thought that the attribute declaration of orderid would avoid the first error, and that the other two attributes wouldn't need to be declared. If the examples are really unclear, the complete xml and xsd is available at http://www.w3schools.com/schema/schema_example.asp Cheers _______________________________________________ libxml-devel mailing list libxml-devel@rubyforge.org http://rubyforge.org/mailman/listinfo/libxml-devel
