RE: validating against the standard W3C
won't say that is it impossible but XMLSpy has a COM based API. So it would be
easier if you wouls use one of the following programming languages C, C++,
VisualBasic, Delphi or scripting languages like VBScript and
i use xmlspy with a java api ...
want to call a validation on the file before uploading to a
validation has to be done in a java context (java api)

for helping, bart
The basic problem
at this point in time is being totally sure of what the gold standard is.
The W3C XML Schema Rec, particularly Part 1, seems almost designed to be
impenetrable. [I have had my knuckles rapped before for saying that, but I
still believe it to be true.]
Inevitably implementors have to
interpret the impenetrable and implementors differ in how they do interpret
it. I would suggest that at this point in the development of XSD Schema (W3C
XML Schema) tools that there is some sort of safety in numbers.
a look at the schema validation facilities in XML Spy and in Turbo XML from
Extensibility. Both are fairly good validators and have free evaluation
downloads available. I spent several weeks working with both downloads on a
range of (relatively brief) schemas. Occasionally Turbo XML (2.2.1 I think)
would miss errors and slightly more often XML Spy (4.01 I think) would
declare spurious errors.
So if you put those validators and their
error messages together with the results from the tool you are already using
then you will begin to (hopefully) creep closer to the truth.
may disagree but for a little time yet I don't think one can safely assume
that the absence of an error message from a W3C XML Schema validation tool
accurately predicts the absence of errors nor does an error message
necessarily accurately predict the presence of errors.
is called for - both in working through the current situation and also in
waiting for the next iteration of (constantly improving) tools.
