Java XML - Java API for XML Processing (JAXP)
About
JAXP (Java API for XML Processing) is an umbrella term that bundle the various low-level XML APIs in JavaSE. ie
- the parser standards Parsers Package (javax.xml.parsers):
- SAX (Simple API for XML) and Streaming API for XML (StAX) standard. (Since version 1.4 of JAXP).
- StAX.
- the Extensible Stylesheet Language Transformations (XSLT) to convert the data to other XML documents or to other formats, such as HTML.
JAXP also provides namespace support support (see javax/xml/namespace), allowing you to work with DTDs that might otherwise have naming conflicts.
- A SAX or DOM API parser
- An XSL processor (to control how XML data is displayed).
