java xml parser

Xml| programming from the date of the birth of XML, it has been the industry's focus on one of the topics. After several years of development, XML technology is becoming more and more mature, now more and more applications are based on XML development. Today, with the increasing popularity of the Internet, distributed

1 DOM DOM (Document Object Model) is a Document Object Model. DOM can access and modify the content and structure of a Document in a way independent of platform and language. In other words, this is a common way to represent and process an HTML or XML document. It is very important that DOM is designed based on the specification of Object Management Organization (OMG), so it can be used in any programming language.DOM is actually a document model desc

quickly. When parsing an XML document using the SAX parser, a series of events are triggered and the corresponding event handlers are activated, and the application accesses the XML document through these event handlers, and the Sax interface is also referred to as the event-driven interface.3, Jdom Way:Jdom is an open source project that uses pure

I name this class xmltest. to read and write the

in advance, occupy less resources; SAX parser code is smaller than DOM parser code, suitable for applets, download. Cons: not persistent; After the event, if the data is not saved, then the data is lost, stateless, only the text can be obtained from the event, but the text is not known which element; use case: Applet; only a small amount of content in an XML doc

For Java, there are two ways to load and parse XML files: One is to generate a document by loading the entire XML file and parse the tree and root of the document content. Another method is to use the sax encapsulation class for gradual parsing. The two methods have their own advantages and disadvantages: the first method is to load the entire

Javain theXMLthe parsing1.dom4jDom parsing principle:The XML parser loads the XML document into memory at once, and then constructs a document object tree in Memory. Gets the node object on the tree through the document object, manipulating the document content through the node Object. dom4j commonly used objects:Saxreader: Reading an

can use Transform-related APIs to Transform memory objects to files. 1) DOMDOM is W3C standard API for processing XML, it is the basis of many other standards related to XML processing, not only Java, other such as JavaScript, PHP, MS. NET and other languages have implemented this standard and become the most widely used XML
