Well, I didn't learn more ... Here is the code I use: XercesDOMParser* parser = new XercesDOMParser();
parser->setDoValidation(true); parser->setDoSchema(true); parser->setDoNamespaces(true); parser->setValidationScheme(XercesDOMParser::Val_Always); parser->setExternalSchemaLocation ( "http://www.elodig.fr/logs file:///path/schema.xsd" ); try { parser->parse ( xmlFile ); } catch (const OutOfMemoryException& toCatch ) { ... And I don't catch any error (see the xml and xsd file at the bottom : there are errors in the xml file). I tried also to load the grammar: parser->useCachedGrammarInParse(true); parser->useCachedGrammarInParse(true); parser->loadGrammar("/path/shcema.xsd", Grammar::SchemaGrammarType, true); Without any success either. Here are the xsd file and then the xml one : <?xml version="1.0" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; targetNamespace="http://www.elodig.fr/logs"; xmlns="http://www.elodig.fr/logs"; elementFormDefault="qualified"> <!-- Defines log data elements --> <xs:element name="data_element"> <xs:complexType> <xs:sequence> <xs:element name="element_name"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="0"/> <xs:maxLength value="30"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="element_value"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="0"/> <xs:maxLength value="100"/> </xs:restriction> </xs:simpleType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> <!-- Defines a log --> <xs:element name="log"> <xs:complexType> <xs:sequence> <xs:element name="id" type="xs:nonNegativeInteger" /> <xs:element name="extension"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:minLength value="0"/> <xs:maxLength value="50"/> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="event_type"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="action" /> <xs:enumeration value="command" /> <xs:enumeration value="result" /> </xs:restriction> </xs:simpleType> </xs:element> <xs:element name="data"> <xs:complexType> <xs:sequence> <xs:element ref="data_element" /> <xs:any minOccurs="0"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="record_time" type="xs:dateTime" /> </xs:sequence> </xs:complexType> </xs:element> <!-- Defines a set of logs --> <xs:element name="logs"> <xs:complexType> <xs:sequence> <xs:element ref="log" /> <xs:any minOccurs="1"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> <?xml version="1.0" encoding="UTF-8"?> <log xmlns="http://www.elodig.fr/logs"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.elodig.fr/logs file:///path/schema.xsd"> <id>1</id> <bubu></bubu> <extension>base</extension> <event_type>action</event_type> <data type="bubu"> <data_element> <element_name>bibi</element_name> <element_value>is happy</element_value> </data_element> <data_element> <element_name>baba</element_name> <element_value>is not happy</element_value> </data_element> </data> </log> According to the xsd file, everywhere where "bubu" appears should trigger an exception. It does not. Any clue? Thanks, - Emmanuel Jesse Pelton wrote: > You may also want to take a look at DOMPrint.
