[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Xerces error report "attribute 'foo' should be qualified"
In my search for a truly conformant W3C schema validating parser (*is* there
really such an animal?) I've just started trying to use Xerces-C (C++, Win
32, VC6). Running the Xerces examples (Sax2Count, for instance) on a simple
document I'm getting some errors that are puzzling me. (I've included the
full content of my instance and schema files at the end of this e-mail.)
Given the following element in my instance document:
<person foo="eh?" bar="what?" legibility="excellent">John Atchley</person>
I am getting the following errors (two of them I WOULD expect). I've added
my puzzlement / comments in brackets:
[1]
Error at file D:\XML\testschema.xml, line 7, char 55
Message: Attribute 'foo' should be qualified
[This error (and the others like it that follow) are most puzzling error to
me. If I qualify this (xmlns:foo="eh?") this message goes away. However,
WHY should I need to qualify this when it is defined in the default
namespace and the parser is obviously finding it in the declaration of
element person in the schema?]
[2]
Error at file D:\XML\testschema.xml, line 7, char 55
Message: Attribute '{}bar' is not declared for element 'person'
[This error does NOT surprise me. Attribute bar is not defined for element
person. I inserted this just to see if the parser was actually finding the
declaration of the element person, which it obviously is. Which only
increases my puzzlement at error 1 above.]
[3]
Error at file D:\XML\testschema.xml, line 7, char 55
Message: Attribute 'legibility' should be qualified
[This is the same as error 1 above. Not only is the parser obviously
finding the declaration of element person with that element's attributes, it
is also properly parsing the declaration of this (referenced) attribute
itself, as evidenced by the next error message!]
[4]
Error at file D:\XML\testschema.xml, line 7, char 55
Message: Datatype error: Type:InvalidDatatypeValueException, Message:Value
'excellent' is not in enumeration .
[This error does NOT surprise me. I intentionally used an invalid value to
make sure that the parser was actually evaluating the attribute declaration
correctly.]
I appreciate any help anyone here can shed on this. If it's a problem with
Xerces I'll hit bugzilla and maybe look at finding the source of the problem
myself. If it's something about schemas that I don't understand then I
*really* need help!
