2. SAX Both DOM and the Simple API for XML (SAX) provide a programmatic layer that allows a user to directly access the information contained within an XML document. However, each of these mechanisms provides a different approach to accessing this information.

3. SAX Whereas DOM creates an object that represents a hierarchical tree of nodes that reflects the structure of an XML document, SAX processes an XML document by giving applications a stream of parsing events around that document.

4. SAX Rather than interacting with an in-memory XML tree, a user is interacting with a stream of data that can be acted upon. DOM is great for in-memory tree manipulation, whereas SAX is great for linear processing of large XML documents. Event-based parsers such as SAX provide a view of XML documents that is data centric and event driven.

5. SAX DOM can also be used for creating documents. Unlike DOM, SAX can only be used for parsing existing documents. parser for the English language might break up a document into paragraphs, words, and punctuation. In the case of XML, the important pieces of data include elements, attributes, text, and so on. This is what SAX does.

6. SAX Some SAX parsers can validate a document against a Document Type Definition (DTD). Validating parsers can also tell you specifically where validation has failed.

7. SAX DOM is an in-memory tree structure of an XML document or document fragment. DOM is a natural object model of an XML document, but it’s not always practical. Large documents can take up a lot of memory.

8. SAX SAX is, in many ways, much simpler than DOM. There is no need to model every possible type of object that can be found in an XML document. This makes the API easy to understand and easier to use.

9. SAX SAX is an event-based API. Instead of loading an entire document into memory all at once, SAX parsers read documents and notify a client program when elements, text, comments, and other data of interest are found. SAX parsers send you events continuously, telling you what was found next. The DOM parses XML in space, whereas SAX parses XML in time.
