XML is a markup language

XML is a markup language much like HTML. It defines the construction and structure of a webpage and helps current browser information in a formatted method. In contrast to HTML, XML does not require the usage of a particular editor. However, it may be edited with any code editor. Browsers will then interpret the tags and current the content material.

Nonetheless, it is vital to notice that not all XML parsers recognize all character encodings, and some character encodings help a subset of Unicode solely. For instance, ASCII doesn’t support some Unicode characters because it does not include code factors for these characters.
