Can You Describe The Difference Between Valid And Well-formed Xml?

Answer»

A well-formed XML is the one which has ROOT element and all TAGS are closed PROPERLY, attributes are defined properly, their value is also quoted properly. On other hand, a valid XML is the one which can be validated against a XSD file or schema. So it's possible for a XML to be well-formed but not valid, because they CONTAIN tags which MAY not be allowed by their schema.
