[lxml-dev] XMLSchema validation with XMLSchema.xsd failing
Can someone advise whether XMLSchema is currently able validate xml schemas. I am on mac 10.4.9 using lxml 1.3 beta using macs default libxml2. In my initial attempt, I am getting the following errors (after catching the exception in the log). I am using XMLSchema.xsd to validate against as you can see. The error comes before my next step - which would validate the schema I am interested in. Here is my session:
import lxml.etree from am.xmlschema import xmlschema_path xmlschema_doc = lxml.etree.parse(xmlschema_path) try: ... xmlschema = lxml.etree.XMLSchema(xmlschema_doc) ... except Exception, e: ... print e.error_log ... /Users/davidpratt/Desktop/xmlschemademo/dev/am.xmlschema/src/am/xmlschema/XMLSchema.xsd:655:ERROR:SCHEMASP:SCHEMAP_REDEFINED_ELEMENT: Element 'element': A global element declaration with the name 'element' does already exist. /Users/davidpratt/Desktop/xmlschemademo/dev/am.xmlschema/src/am/xmlschema/XMLSchema.xsd:864:ERROR:SCHEMASP:SCHEMAP_REDEFINED_ELEMENT: Element 'element': A global element declaration with the name 'group' does already exist.
Many thanks Regards David

Yes, that's its purpose.

That *might* be a problem. XML Schema support is still being worked on in libxml2 and there may still be schemas that don't work. However, MacOS-X is known for not shipping with up-to-date versions of libxml2, so you might have more luck with installing a newer version.

If you are sure the document is correct (and it's usually a good idea to verify with a second tool), a more recent version of libxml2 might help. Otherwise, please file a bug report on libxml2's XML Schema implementation. Stefan
