What is an XML Validator?

An XML (eXtensible Markup Language) Validator is a tool that checks if an XML document is well-formed. A well-formed XML document follows all the basic syntax rules of XML, such as having a single root element, all elements being properly nested, and all tags being correctly closed. This is crucial for ensuring that the XML data can be correctly parsed and processed by applications.
