Semantics of XML tags
Although XML document type definitions provide a mechanism for describing the syntax of the XML language in a machine-readable form, there is currently no similar mechanism for specifying the specific semantics of an XML vocabulary.

R language XML format data import and processing - ShangFR
XML is an extensible markup language designed to transmit and store data. XML is the most commonly used tool for data transfer between various applications. It is different from databases such as Access, Oracle and SQL Server.

In fact, the biggest difference between it and other data representations is that it is extremely simple. This is a seemingly trivial advantage, but it is this that makes it unique.

XML Http Request latest alternative technology - Fetch
In web applications, JavaScript performs asynchronous requests through XMLHttpRequest (XHR), which is a technology that effectively improves page communication. When we talk about Ajax technology, we usually mean Ajax based on XMLHttpRequest. Although Ajax is useful, it is not the best API. It is not designed to comply with the principle of separation of duties, mixing input, output, and state tracked with events into a single object. Moreover, the event-based model runs counter to the popular Promise and generator-based asynchronous programming models in JavaScript today. What this article will introduce is XMLHttp

XML—DOM4J for XML parsing
Dom4j is a simple, flexible open source library. Dom4j was split off from the early developers of JDOM and then developed independently. Unlike JDOM, dom4j uses interfaces and abstract base classes. Although Dom4j's API is relatively complex, it provides better flexibility than JDOM.

XML—SAX for XML parsing
When using DOM to parse an XML document, you need to read the entire XML document, build the Document object of the entire DOM tree in memory, and then operate on the XML document. In this case, if the XML document is particularly large, it will consume a lot of computer memory, and in severe cases may even cause memory overflow.
