------------------------------------
Summary: XERCES-J 2-11 beta - xsd:boolean value "1" not treated in
the same way as "true" when dealing with XSD 1.1 assertions
Key: XERCESJ-1632
URL: https://issues.apache.org/jira/browse/XERCESJ-1632
Project: Xerces2-J
Issue Type: Bug
Affects Versions: 2.11.0
Environment: Windows 64bit
Reporter: George Cowe
I've been using Xerces-J 2-11 with support for XML Schema 1.1
(Xerces-J-bin.2.11.0-xml-schema-1.1-beta.zip)
I've noticed that it does not seem to treat the xsd:boolean value of "1" in the
same way as it treats the value "true".
"0" and "false" are treated correctly.
This is in the context of assertions only, Xerces-J 2-11 without the schema 1.1
support seems to be ok.
The example below demonstrates the issue.
If 'success_ind' is true or 1 then the assertion should catch the error.
The example below passes schema validation when it shouldn't
<?xml version="1.0" encoding="UTF-8"?>
<test:message xmlns:test="http://test/schema/v1";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://test/schema/v1 test.xsd">
<test:success_ind>1</test:success_ind>
<test:error>Error details appear here</test:error>
</test:message>
This example below fails schema validation as expected
<?xml version="1.0" encoding="UTF-8"?>
<test:message xmlns:test="http://test/schema/v1";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://test/schema/v1 test.xsd">
<test:success_ind>true</test:success_ind>
<test:error>Error details appear here</test:error>
</test:message>
Using the schema test.xsd with the appropriate assertion
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:test="http://test/schema/v1";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://test/schema/v1";
elementFormDefault="qualified"
attributeFormDefault="qualified"
version="1.0">
<xsd:complexType name="Message">
<xsd:sequence>
<xsd:element name="success_ind" type="xsd:boolean"/>
<xsd:element name="error" type="xsd:string" minOccurs="0"/>
</xsd:sequence>
<xsd:assert test="if (test:success_ind = false()) then test:error else
true()"/>
<xsd:assert test="if (test:success_ind = true()) then not(test:error)
else true()"/>
</xsd:complexType>
<xsd:element name="message" type="test:Message"/>
</xsd:schema>
Sample Code
public boolean xmlValidate(String xmlFile, String schemaFile)
{
boolean valid = true;
File validatingXMLFile = new File(xmlFile);
File schemaXMLFile = new File(schemaFile);
try
{
StreamSource schemaDocument = new
StreamSource(schemaXMLFile);
Source instanceDocument = new
StreamSource(validatingXMLFile);
SchemaFactory sf =
SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1";);
Schema s = sf.newSchema(schemaDocument);
Validator v = s.newValidator();
v.validate(instanceDocument);
System.out.println(xmlFile + " is valid");
}
catch (Exception e)
{
System.out.println(xmlFile + " is not valid, exception=" +
e.getMessage());
return false;
}
return valid;
}
