Types of Parsers

DOM Parser: DOM parsers parse an entire XML document into a tree structure, allowing easy navigation and manipulation of the document elements. This approach is suitable for small to medium-sized XML documents where the entire document can fit into memory.

SAX Parser: SAX parsers are event-driven parsers that parse XML documents sequentially. They don't build an in-memory representation of the entire document but instead trigger events as they encounter XML elements. SAX parsing is memory-efficient and suitable for large XML documents.

Create a Parser Factory: Use the DocumentBuilderFactory class to obtain a new instance of a DOM parser.

Configure the Parser: Optionally, configure the parser settings such as namespace awareness, validation, and schema validation.

Obtain a Parser: Use the factory to create a new DOM parser instance.

Parse the XML Document: Use the parser to parse the XML document and obtain a DOM tree.

Process the Document: Once parsed, you can traverse the DOM tree, extract data, and perform operations on the XML document.
