XML
XML (eXtensible Markup Language) has been used in the Java EE

platform since the beginning of deployment descriptors and metadata information.

XSD
XML Schema Definition (XSD) is an XML-based grammar declaration used to

describe the structure and content of an XML document

name="expiry_date" type="xs:string"/>

Parsing with SAX and DOM
The Document Object Model (DOM) API requires

reading the entire XML structure and holding the object tree in memory.
The Simple API for XML (SAX) is an event-driven, serial-access mechanism that does element-by-element processing

Querying in XML
XPath
//content/order_line[unit_price>=20]/unit_price/text()
XQuery
for $orderLine in doc("order.xml")//content/order_line[@quantity>1]
where $orderLine/unit_price < 50
return $orderLine/unit_price/text()

XSLT
eXtensible Stylesheet Language Transformations (XSLT ) allows to transform an XML

document from one vocabulary to another, in a generic manner

JAXB
Java Architecture for XML Binding (JAXB) allows developers to work with

Java objects that represent XML documents
@XmlRootElement annotation
marshaller.marshal(person, writer);
Generate XSD from Java class
jaxbContext.generateSchema(sor);

JSON
JSON (JavaScript Object Notation) originated with JavaScript for representing simple data

structures
