By "cross validate" I mean :
say Party1 provides an XML document to party2 and before that party1 sends the
corresponding XSD document to party2.
how does party2 validate the given XML document ? There may be many
goofing things, Manual validation does not work for an XML document
containing 1000s of records.
as, had it been in DTD, the parser would have validated the XML document[say IE
browser]. Because DTD is defined in same XML document itself and DTD itself is
not a separate doc as opposed to XSD.
what my understanding is. Can you please correct me ?
In terms of validation functionality, XSD can define all
the constraints that a DTD can define, and many more. To take a simple
example, XSD can say that a particular attribute must be a valid date, or a
number, or a list of URIs, or a string that is exactly 8 characters long. To
take another example, XSD can define much richer constraints on uniqueness of
values within a document.
I've no idea what you mean by "cross validate". I believe
the only things you can do with a DTD that you can't do with an XML Schema are
things that have nothing to do with validation: notably, defining
Can anybody please explain me the real difference between XSD
and DTD. Because both are used to define the schema of an XML
Whereas DTD is more powerful in the sense that XML parser can cross
validate an XML document based on its DTD, and this is really useful in
business world as XML is mostly used to exchange the data between
the other hand XSD defines the schema in XML syntax only which is more
readable, but XML parser CAN NOT cross validate one XML document based on a
Then I am not understanding why people go for XSD
Can some body correct me please !
