jaxp means java api for xml processing, it's obviously more convenient than dom4j, jdom etc..
The DOM parser is called a
DocumentBuilder , as it builds an in-memory Document representation. The javax.xml.parsers.DocumentBuilder is created by the javax.xml.parsers.DocumentBuilderFactory . The DocumentBuilder creates an org.w3c.dom.Document instance, which is a tree structure containing nodes in the XML Document. Each tree node in the structure implements the org.w3c.dom.Node interface. There are many different types of tree nodes, representing the type of data found in an XML document. The most important node types are: from: http://en.wikipedia.org/wiki/Java_API_for_XML_Processing
