JAXP (Java API for XML Processing) is a standard API for working with XML documents in Java. It provides an abstraction over specific implementations of XML parsers and XSLT processors.
Main components of JAXP:
- SAX (Simple API for XML): Event-driven parser. Processes the document sequentially, generating events (start/end element, character data, etc.) as it reads. Suitable for large documents with low memory consumption.
- DOM (Document Object Model): Tree-based parser. Loads the entire XML document into memory as a tree structure, allowing easy navigation and modification. Requires more memory for large documents.
- StAX (Streaming API for XML): Incremental parser. Provides cursor-based access to XML elements, combining the advantages of SAX (low memory usage) and DOM (more convenient data access).
- XSLT (Extensible Stylesheet Language Transformations): API for transforming XML documents using XSLT stylesheets.
Example of using DOM parser:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import java.io.File;
// Creating a DocumentBuilder factory
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
// Getting a DocumentBuilder instance
DocumentBuilder builder = factory.newDocumentBuilder();
// Parsing the XML file
Document doc = builder.parse(new File("example.xml"));
// Now you can work with the document via DOM API
