No validation error message when the root element is erroneous
Hi all.
I am using the 2.9.0 Java version.
First at all, I am loading the complete grammar pool of the Schema files in
one parser object.
And then, when I am trying to validate an XML file, if the root element of
this XML file is incorrect (with a different namespace and/or with a
different name), I don't receive any error message in the Error handler.
Can you help me?
Thanks in advance.

Ok. When I have disabled "dynamic validation" the error message event is
launched.
Thanks to Michael and Stanimir.
Regards.

If I'm not missing something you need to disable the dynamic
validation, instead.

It's due to having the dynamic validation feature enabled. If you want an
error to be reported you need to turn it off.

Re: No validation error message when the root element is erroneous

Hi Michael
Yes, you are right.
But what I mean is, for example: the root element of my XML file has the
"MD_Metadata" name.
I'm completely sure that in the Schema Grammar this element is included so
it is possible to validate the rest of the XML file. And, in this case,
everything is correct.
But, I have verified that, if I change this root name by other string (not
defined in the schema) then it never reports an error. Not even the first
error message that I'm expecting, something like: "The root element is not
defined in the schema files" or similar.
Is it due to the Parser can't find the root element and then nothing is
validated?
Please tell me if now I have explained correctly my question.
Besides I append the "features configuration" I define in my program before
the validation, as you can see the "dynamic" option is activated.
parserObject.setFeature("http://xml.org/sax/features/validation", true);
parserObject.setFeature("http://apache.org/xml/features/validation/dynamic",
true);
parserObject.setFeature("http://apache.org/xml/features/validation/schema",
true);
parserObject.setFeature("http://apache.org/xml/features/validation/schema-full-checking",
true);
parserObject.setFeature("http://xml.org/sax/features/namespaces", true);
Thanks and regards
Alberto

Hi Alberto,
Not sure what you mean by "the root element of this XML file is
incorrect". Any element with a top-level declaration in your schema could
potentially be used as a root element. Did you mean that the element isn't
declared anywhere? If that's the case, you should check if you have the
dynamic validation [1] feature enabled (don't set it to true if that's not
the behaviour you want).
Thanks.
