Hi All,
we are using libxml2 in order to validate our xml schemas. The xsd files
are organized as stated in the following:
* RichiestaSAIA.xsd (targetNamespacePrefix: ap5) includes
ComAnagTypes.xsd and imports RichiestaAPR4.xsd
* ComAnagTypes (targetNamespacePrefix: ap5) includes
RichiestaMacroTypes.xsd
* RichiestaMacroTypes.xsd (targetNamespacePrefix: ap5) includes
BaseTypes.xsd
* RichiestaAPR4.xsd (targetNamespacePrefix: apr4) imports BaseTypes.xsd
A picture of the schemas structure has been attached. The libxml2
validation function reports the following error:
/Warning: DOMDocument::schemaValidate(): Element
'{http://www.w3.org/2001/XMLSchema}import': The schema document
'BaseTypes.xsd' cannot be imported, since it was already included or
redefined. /
All the other validation tools, W3C Schema validation service, XMLSpy,
XML-Beans, validate the schemas without reporting any error or warning.
Can anyone suggest an explanation for this problem ? Thanks in advance.
Luigi
