What is difference between XML and XSD?

XML: XML that is short for Extensible Markup Language is a set of rules that governs the encoding of documents into an electronic format. XML and HTML make a great combination together. Through XML the structure of the document can be defined but not the way the document is displayed, it is handled by the HTML. It is not possible to define any elements or tags that are usable within the document.

A tag can be created to describe any element on the XML document as long as the correct structure is followed. The work of XML is to only check how well-formatted the document is, this can still be a problem as some well-formatted document can still have some errors in it. XSD validating software most of the time catch the errors that the XML validating software might miss.

XSD: XSD is short for the XML Schema Document. It is one of the schema languages that are included in the XML. This defines what can be included in the documents. One of the strengths of XSD is that it is written in XML. Most of the people who know XML must be already familiar with XSD, and this eliminated the need to learn a new language.

In XSD elements can be defined and can also be used in the document, in addition, they can relate to the actual data with which it is to be encoded. The plus point of having a defined data type and elements is that the information will be properly interpreted. The previously mentioned is justified because the sender and the receiver know the format of the content that is being communicated. The documents of XSD always follow the structure of the XML, and it is always validated as an XML document. The developers can use the XML parsers to parse the XSD documents and it will perform flawlessly, also the information that will be produced by the file will be correct, the opposite of this is not possible because an XML document can contain elements that may not be recognized by the XSD parser.
