Xml parser
- 1. XML Parser
- 2. HTML VS XML
- 3. XML Parsers ➢ An XML parser is a software library or package that provides interfaces for client applications to work with an XML document. ➢ The XML Parser is designed to read the XML and create a way for programs to use XML. ➢ XML parser validates the document and check that the document is well formatted
- 5. Types of Xml Parsers There are 2 main types they are: ➢ DOM ➢ SAX
- 6. Features: ➢ A DOM Parser creates an internal structure in memory which is a DOM document object and the client applications get information of the original XML document by invoking methods on this document object. ➢ DOM Parser has a tree based structure. DOM (Document Object Model) Advantages: ➢ It supports both read and write operations and the API is very simple to use. ➢ It is preferred when random access to widely separated parts of a document is required. Disadvantages: ➢ It is memory inefficient. (consumes more memory because the whole XML document needs to loaded into memory). ➢ It is comparatively slower than other parsers.
- 8. Features: A SAX Parser implements SAX API. This API is an event based API and less intuitive. SAX (Simple API for XML) Advantages: ➢ It is simple and memory efficient. ➢ It is very fast and works for huge documents. Disadvantages: ➢ It is event-based so its API is less intuitive. ➢ Clients never know the full information because the data is broken into pieces.
