Hi guysI'm having major problems with libxml-ruby version 0.9.8 on Mac OS X 10.5.6. The gem installs without problems, but schema validation errors result in a Bus Error or Segmentation Fault.
The problem doesn't occur when the same code is run against 0.9.7, nor does it occur with 0.9.8. on Ubuntu.
I have constructed the following sample program which illustrates the problem:
-----------------------[ validate.rb ]---------------- require 'rubygems' require 'libxml' include LibXML if ARGV.length < 2 puts 'Wrong number of arguments' puts 'ruby validate.rb path/to/schema/file path/to/xml/file...' exit 1 end schema = XML::Schema.document(XML::Document.file(ARGV.shift)) ARGV.each do | xml_file_name | instance = XML::Document.file(xml_file_name) result = instance.validate_schema(schema) do |message, is_error|puts "#{is_error ? 'ERROR' : 'WARNING'}: #{xml_file_name}: #{message}"
end
puts "#{xml_file_name} is #{result ? 'VALID' : 'INVALID'}"
end
--------------------------------------------------
-----------------------[ schema.rb ]----------------
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
targetNamespace="http://not.important/status";
xmlns:tns="http://not.important/status";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:complexType name="Release">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="state" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:element name="release" type="tns:Release"/>
</xs:schema>
---------------------------------------------------
-----------------------[ sample1.xml ]---------------
<?xml version="1.0" encoding="UTF-8"?>
<release xmlns="http://not.important/status";>
<Name>release</Name>
<state>Ready</state>
</release>
---------------------------------------------------
Running validate.rb with the schema and sample xml file should
generate a validation error since the 'name' element is misspelled.
But instead (on Mac OS X) I get
$ ruby validate.rb schema.xsd sample1.xml validate.rb:16: [BUG] Segmentation fault ruby 1.8.6 (2008-03-03) [universal-darwin9.0] Abort trap With 0.9.7 I getError: Element 'release' [CT 'Release']: The element content is not valid. at sample1.xml:0. validate.rb:16:in `validate_schema': Error: Element 'release' [CT 'Release']: The element content is not valid. at sample1.xml:0. (LibXML::XML::Error)
from validate.rb:16
from validate.rb:14:in `each'
from validate.rb:14
On Ubuntu, 0.9.8 gives me
Error: Element '{http://not.important/status}Name': This element is
not expected. Expected is ( {http://not.important/status}name ). at
sample1.xml:3.
validate.rb:16:in `validate_schema': Error: Element '{http://not.important/status
}Name': This element is not expected. Expected is ( {http://not.important/status
}name ). at sample1.xml:3. (LibXML::XML::Error)
from validate.rb:16
from validate.rb:14:in `each'
from validate.rb:14
which is spot on.
ruby --version on the Mac yields
ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]
and on Ubuntu
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
