how to parse xml in java

start, end, text, start, or end of an element, it sends events and programmers write code to respond to these events and save data. Advantage: the entire document does not need to be transferred in advance, which consumes less resources. Disadvantages: it is not persistent. After an event, if no data is saved, the data is lost; stateless; only the text can be obtained from the event, but the element of the text is unknown; Usage scenarios: only a small amount of content in the

Currently, there are many techniques for parsing XML in Java, such as Dom, SAX, JDOM, dom4j, and the advantages and disadvantages of these 4 kinds of parsing XML document technologies are described below.First, define an interface XmlDocument that operates an XML document, which defines the interface for creating and p

, and attribute values.Important JDOM classes:org.jdom2.input.DOMBuilder:Use the DOM parsing mechanism to parse XML and convert it to a JDOM Document object.org.jdom2.input.SAXBuilder:Use the SAX parsing mechanism to parse XML and convert it to JDOM Document.org.jdom2.input.StAXEventBuilderAndorg.jdom2.input.StAXStream

When a given tag is found, it can activate a callback method to tell the method that the tag has been found. SaxMemory requirements are usually relatively low, because it allows developers to determine the tag to be processed by themselves. Especially when developers only need to process part of the d

XML has now become a universal Data Interchange format, its platform-independent, language-independent, system-independent, to the data integration and interaction brought great convenience. The syntax and technical details of the XML itself need to be read in the relevant technical literature, which includes the DOM (document Object Model), the DTD (document Type Definition), SAX (Simple API for
