that of SAX (Simple API for XML) andDom (Document Object Model ). JAXP's goal is very simple: to make the use of Sax and Dom easier, especially in the field of vendor-neutral.
JAXP is a package API
Initially, JAXP was designed to provide convenience and vendor neutrality to Sax and Dom. Based on this, JAXP has never thought of replacing sax orDom; in fact, JAXP has some methods in earlier versions. getxmlr

Java and XML are a combination of gold. Many articles on the Internet have introduced that XML, as a data exchange in e-commerce, has become irreplaceable. However, during system development, we may not all use data exchange. Is it impossible to use XML?
Of course not. Now there is a new trend. The configuration files

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

Overview:
JDOM is a new API function that reads, writes, and operates XML in Java. Jason Hunter and Brett McLaughlin publish their beta versions. These API functions are optimized to the maximum extent on the premise of intuition, simplicity, and efficiency. In the following sections, Hunter and McLaughlin will introduce how to use JDOM to read and write an existing

Well, so far, we've mastered two great tools for XML programming: DOM and sax, and how to use them in a Java program. DOM programming is relatively simple, but it is slower, consumes more memory, and sax programming is complex, but fast and consumes less memory. Therefore, we should choose to use different methods according to different
XML has now become a general Data Interchange format, its platform independent, language-independent, system-independent, which brings great convenience to data integration and interaction. For the syntax knowledge and technical details of the XML itself, it is necessary to read the relevant technical literature, which includes the DOM (document Object Model), th
Marshaller and unmarshaller can be used to implement conversion between Java object and XML.
