XML programming-DOMXML parsing Technology

There are two kinds of xml parsing techniques commonly used: dom parsing and sax parsing.

Dom: (Document Object Model, the document object model) is a way of dealing with XML recommended by the W3C organization.

Sax: (Simple API for XML) is not the official standard, but it is the de facto standard of the XML community, and almost all XML parsers support it.

Jaxp introduction

Jaxp (Java API for XML Processing) is a development kit for Java to program XML. It consists of javax.xml, org.w3c.dom, org.xml.sax packages and their subpackages.

In the javax.xml.parsers package, several factory classes are defined, and programmers call these factory classes to get DOM or SAX parser objects that parse the xml document.
