The Extensible Markup Language (XML) is a general-purpose markup language. It is classified as an extensible language because it allows its users to define their own elements. Its primary purpose is to facilitate the sharing of structured data across different information systems, particularly via the internet. It is used both to encode documents and serialize data.
XML is a framework for defining markup languages:
Main features of XML:
XML

That depends on what you want to do, xml tools include; xml parsers xml validators xml editors xml schema editors xml code generators
what are the component of xml document what are the component of xml document
there is no source code, xml is not a programming language, its a markup language for which you create your own tags, the basic xml syntax is <xml> to start an xml file, and </xml> to end the xml file.
it is the same way to create xml file by converting into txt you have to use the correct xml syntax ie <xml> this is to denote strat of xml file and this </xml> denotes end of xml file. You have to use the right xml code or your xml file wont be valid or well formed.
There are two current versions of XML. The first XML 1.0 was initially defined in 1998 and it has undergone minor changes/revisions since then. Though changes have been done, a new revision number has not been assigned to this version. It is called XML 1.0 5th edition, with the latest edition (5th) being released on 26th Nov 2008. The second version XML 1.1 was initially published on 4th Feb 2004, the same day as the XML 1.0, 3rd edition. XML 1.1 is currently in its 2nd edition which was released on 16th Aug 2006. It contains certain features that are expected to make XML easier to use.
A browser is the tool that takes the xml and stylesheets associated with it and presents it for viewing. If there are not stylesheets associated with the xml, then the browser presents the text of the xml file only. Some browsers have an xml viewer to view the xml text in a more organized fashion. A browser refers to a software application that can help you browse the world wide web a.k.a the internet. The browser contains features using which it can interpret the data sent by the web servers and display them into stuff that the user can understand. Ex: Mozilla firefox, Internet Explorer, Safari, Google Chrome etc.
If you open the xml in most web browser it will state an error code denoting the type of malformation of the xml. you can use an xml tool like an xml editor to validate and correct your xml.
If you use an xml tool like liquid xml studio or any other xml tool you will be able to convert your xml into an xsd or dtd.
XML Schema is an XML-based alternative to DTD.An XML schema describes the structure of an XML document.The XML Schema language is also referred to as XML Schema Definition (XSD).An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself.
XML is a language used to store data. XSLT is a language which is used to transform XML into other XML.
