[xml] No matching global declaration available for the validation root

["CAPRON Patrick" <capronpa e-i com>]

Hi,

 

I try to use libxml2 to generate an XML file and before creating it, I would like to validate it against an existing schema.

 

If I use the xmlSchemaValidateDoc function to validate my xmlDocPtr (created with xmlNewDoc, xmlNewNode, xmlDocSetRootElement, etc...)

I get this error message (Document is the name of the root element in my XML document) :

element Document: Schemas validity error : Element 'Document': No matching global declaration available for the validation root.

Then if I first save the file using xmlSaveFileEnc, reopen it by xmlParseFile the xmlDocPtr that I get can be validated against the same schema without any problem...

 

Has anybody an explanation ?

Must I do something to my xmlDocPtr in order to be able to validate it ?

 

Thanks for you help.
