assert instruction in XSD
---------------------------------------------------------------------------------------------------
Key: XERCESJ-1538
URL: https://issues.apache.org/jira/browse/XERCESJ-1538
Project: Xerces2-J
Issue Type: Bug
Components: JAXP (javax.xml.validation)
Affects Versions: 2.11.0
Environment: Windows 7 x64, Java 6 Update 26 x64
Reporter: Denis Orekhov
I'm using Xerces2 Java 2.11.0 (XML Schema 1.1) (Beta) in my app. Schema
validation in my app can occurs simultaneously in separate threads.
This is part of my xsd:
<xs:element name="action">
<xs:complexType>
<xs:all>
<xs:element name="main_context" minOccurs="0" />
<xs:element name="navigator" minOccurs="0">
<xs:complexType>
<xs:attribute name="element"
type="xs:string" />
<xs:attribute name="refresh"
type="xs:boolean" />
</xs:complexType>
</xs:element>
<xs:element name="datapanel" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element
name="element" maxOccurs="unbounded"
minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element name="add_context" minOccurs="0" />
</xs:sequence>
<xs:attribute name="id" type="xs:string" use="required" />
<xs:attribute name="refresh_context_only" type="xs:boolean" />
<xs:attribute name="skip_refresh_context_only"
type="xs:boolean" />
<xs:attribute name="keep_user_settings" type="xs:boolean" />
</xs:complexType>
</xs:element>
</xs:sequence>
<xs:attribute name="type"
type="xs:string" use="required" />
<xs:attribute name="tab"
type="xs:string" />
</xs:complexType>
</xs:element>
<xs:element name="server" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element
name="activity" minOccurs="0" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="add_context" minOccurs="0" />
</xs:sequence>
<xs:attribute name="type" type="xs:string"
use="required" />
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:all>
<xs:assert
test="(count(datapanel) + count(server) =0) or
(count(*[position()=1 and name()='main_context']) = 1)" />
</xs:complexType>
</xs:element>
And sometimes I have SAXException with text "cvc-assertion.3.13.4.1: Assertion
evaluation ('(count(datapanel) + count(server) =0) or (count(*[position()=1 and
name()='main_context']) = 1)') for element 'action' with type '#anonymous' did
not succeed.".
I checked my data and schema text before validation error - both is good.
