Hi
I am testing XML vs XSD validation using the Xerces-C++.
I have an XML which contains an invalid tag <OffersLookupService1> and my
XSD contains the valid <OffersLookupService>, when I run the following
code, it validates my XML without error. I'm rather expecting to fail.
XERCES_CPP_NAMESPACE::XercesDOMParser dom_parser;
XMLValidator_ParserErrorHandler error_handler;
dom_parser.setErrorHandler(&error_handler);
dom_parser.setValidationScheme(XERCES_CPP_NAMESPACE::XercesD
OMParser::Val_Auto);
dom_parser.setDoNamespaces(true);
dom_parser.setDoSchema(true);
dom_parser.setValidationConstraintFatal(true);
dom_parser.useCachedGrammarInParse(false);
dom_parser.setExitOnFirstFatalError(true);
dom_parser.setValidationSchemaFullChecking(true);
// dom_parser.setExternalNoNamespaceSchemaLocation(my_schema_
source.c_str());
XERCES_CPP_NAMESPACE::MemBufInputSource in_memory_schema_buffer((XMLByte*)
my_schema_source.c_str(), my_schema_source.size(), "my schema buffer");
if (dom_parser.loadGrammar(in_memory_schema_buffer,
XERCES_CPP_NAMESPACE::Grammar::SchemaGrammarType) == NULL) // ,true to cache
{
request_details->setError(SchemaError_DOMParserCouldNotLoadSchema, "Failed
to load schema");
return false;
}
try
{
XERCES_CPP_NAMESPACE::MemBufInputSource in_memory_xml_buffer((XMLByte*)
my_xml_source.c_str(), my_xml_source.size(), "my xml buffer");
dom_parser.parse(in_memory_xml_buffer);
if (dom_parser.getErrorCount() == 0)
{
request_details->setError(Validation_OK, "");
<-------------------------------------
ALWAYS SUCCEEDS ? Why?
}
else
{
request_details->setError(XMLError_FileDoesNotConformToSchema, "Schema
validation failed");
}
....
When I use the online validator (http://www.utilities-online.i
nfo/xsdvalidation/#.WMqyD_mLRaQ) it fails as expected with error:
"Not valid.
Error - Line 6, 24: org.xml.sax.SAXParseException; lineNumber: 6;
columnNumber: 24; cvc-complex-type.2.4.a: Invalid content was found
starting with element 'OffersLookupService1'. One of
'{OffersLookupService}' is expected."
my_xml_source in abovementioned code contains this XML:
<?xml version="1.0" encoding="UTF-8"?>
<Get>
<OffersLookupService1>
<Transaction>
(... simplified for clarity .... )
</Transaction>
</OffersLookupService1>
</Get>
my_schema_source in abovementioned code contains this XSD:
<?xml version='1.0' encoding='utf-8'?>
<xs:schema xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
attributeFormDefault='unqualified' elementFormDefault='unqualified'
xmlns:xs='http://www.w3.org/2001/XMLSchema'>
<xs:element name='Get'>
<xs:complexType>
<xs:sequence>
<xs:element name='OffersLookupService'>
<xs:complexType>
<xs:sequence>
<xs:element name='Transaction'>
<xs:complexType>
<xs:sequence>
<xs:any minOccurs='1' namespace='http://www.nrf-arts.org/IXRetail/namespace/'
processContents='lax' />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name='version' type='xs:string' use='required' />
</xs:complexType>
</xs:element>
</xs:schema>
Could someone please explain why is Xerces not failing in this case? Is
there misconfiguration in my code?
Many thanks.
