What is XML?
XML (eXtensible Markup Language) is an open data format for structuring, storing, and transmitting data over a network using a human-readable text format. XML language markup is similar to HTML. XML is independent of any programming language, software, or hardware, and can be easily parsed into syntactic constructs by XML processors. XML data format is widely used to store and transfer data objects over the network, during client-server interactions in enterprise applications. The XML format is informative and easy to understand. The MIME type for XML files is application/xml. XML files use the *.xml extension.
Why format and validate XML?
To save bandwidth, many applications minify XML files before transferring XML data over the network. This does not affect the data in the XML file, but it makes the code unreadable to humans. XML minification can sometimes lead to invalid XML, which can corrupt the data being transferred and interfere with applications that use the XML. XML data errors can be difficult and time-consuming to locate. You can troubleshoot XML errors by using an online tool that formats XML and indicates errors, such as ReqBin Online XML Formatter and Validator.
