How validating parsers use xml schema namespace
DTDs allow for basic control of element and attribute names and the overall structure of an XML document. The following XML document could be validated with the brief DTD that follows: *Technically speaking, there are ways to write a DTD that allow validating parsers to handle multiple namespace prefix schemes.The somewhat complex technique involves using an entity for the prefix and indirectly mapping all the element names in the content model to include the prefix entity.By convention, XML is serialized as a text document.A parser is a piece of software which reads the document and handles the intricacies of the XML format for the programmer.Some parsers can also validate the document against a schema.Validates the XML string/file against the specified XSD string/file.
We’ll begin with brief introductions and examples of several validation methods.
Choose your DTD namespace approach depending on what you’re trying to accomplish with your DTD.
The default namespace approach is easier if you’re not mixing namespaces and just want a simple validation.
XSD files are "XML Schemas" that describe the structure of a XML document.
The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.
