What is the difference between XML & HTML? o XML describes data, HTML displays data. o HTML has predefined tags, in XML we define tags o HTML can be displayed on its own, XML cannot. The combination of XML and HTML is XHTML. 3. What is a "well-formed" document? The well formed document must obey the basic XML constraints like : o All Documents must have a prolog. o Document must have a root tag. o All begin-tags must have end-tags. (case sensitive) o All attribute values must be quoted. o Elements must be properly nested. o All entities must be declared. If a document is not a well-formed document it is not a XML document. 4. What is DTD? Document Type Definition defines the structure of an XML document. A DTD can be declared inline in your XML document, or as an external reference. DTD defines : o What element (tag) names are allowed o What attributes are used with each element o Which child elements belong to which parent elements o What order child elements can appear in o Also declares entities and notations 5. What are the building blocks of XML? o Elements o Attributes o Entities o Notations 6. What is a valid document If a document's structure and tag names match the information model, it is 'valid'. Validation is optional. A valid document is always well-formed. 7. What is XSLT? XSLT is a language for transforming the structure of XML documents. The XSL Transformations (XSLT) vocabulary provides a rule-based framework for select ing and processing document content, and transforming it into new documents 8. What is XML Parser? A set of software components designed for reading, processing and creating X ML documents. Parsers expose the structures and tags within a XML document thus making it easy to process XML documents. 9. What are the types of Parsers DOM Vs SAX o SAX is event-based and DOM is object-based o SAX is developed by XML-Dev mailing list and DOM is a W3C recommendation o DOM constructs a tree in memory and SAX does not o SAX is read-only and DOM is read-write. o SAX uses less memory and is fast & efficient We also have Validating and non-validating parsers. |
