xml document validation againsta schema
---------------------------------------
Key: XERCESC-1736
URL: https://issues.apache.org/jira/browse/XERCESC-1736
Project: Xerces-C++
Issue Type: Bug
Components: Validating Parser (DTD), Validating Parser (Schema)
(Xerces 1.5 or up only)
Affects Versions: 2.7.0
Environment: Windows XP professional
Visual Studio 2005
Reporter: Denis Tkachov
Instances of both XercesDOMParser and SAX2XMLReader threat all the documents
as valid even if a document does not match schema provided.
In order if document does not match schema provided the library does not throw
exception and getErrorCount method of the parser returns zero.
So it seems to be a bug in the library.
As example you can try this code:
http://xml.apache.org/xerces-c/program-dom.html#ConstructXercesDOMParser
Below are provided scheme and document (error marked with "does not match
schema" comment) that reproduces error:
datasetSchema.xsd:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="DataObject">
<xs:complexType>
<xs:choice minOccurs="0" maxOccurs="unbounded">
<xs:element name="MasterDataTable">
<xs:complexType>
<xs:sequence>
<xs:element name="key"
type="xs:int"/>
<xs:element name="name"
type="xs:string"/>
<xs:element
