How to validate incoming requests in a Golang API
Article Introduction：Using structure tags combined with go-playground/validator library is the best practice for verification requests in GoAPI. It can ensure data integrity, security and behavioral predictability; by adding validate tags (such as required, email, min, max, etc.) to structure fields, and parsing JSON in the processor for verification, clear and maintainable verification logic can be achieved; for simple scenarios, manual verification can be used to check field validation through type assertions and conditions; middleware can also use unified processing of public verification (such as header information, query parameters), and through regular or dedicated libraries (such as gorilla/sc

How to modify content using Java in XML
Article Introduction：When Java modify XML, you need to select the parsing library according to the XML file size and modification complexity: DOM (small file, simple modification), SAX/StAX (large file, complex modification). When using DOM parsing, first use the factory class to create a DocumentBuilder, load and parse XML files, and then use the DOM API to operate the node; when using SAX parsing, you need to record the node information and rebuild the XML fragment when modifying. In addition, pay attention to common pitfalls such as exception handling, coding issues, XPath usage and performance optimization, and follow best practices such as using appropriate libraries, writing clear code, fully testing and considering XML Schema validation to write efficient, maintainable XML modification code.
