Difference Between XML and XAML.

XML, or Extensible Markup Language, is a subset  of the more complex SGML (Standard Generalized Markup Language). XML makes use  of syntax tags that helps to identify the various data  types in a file. XML is referred to as a metalanguage that describes other  languages. It is part of the large markup language family that was created by  the World Wide Web Consortium (W3C). XML, unlike HTML  (another Markup Language), was made optionless so that the data  remains uniform in different browsers. XML pages are much more flexible than  HTML pages which will definitely help XML replace HTML in the future.

XAML, or Extensible Application Markup Language,  is a declarative XML-based markup language that is part of the Microsoft suite.  It helps in the visual presentation of an application developed in Microsoft  Expression Blend. This application can either be created by hand or visually  using Design View of Expression Blend. In both cases you end up writing XAML  code. XAML allows you to initialize objects and set their properties using a  hierarchical relationship. It uses the period  notation to define the attribute as a property of the object. You can even build  visible UI elements using XAML. XAML can seamlessly move around different tools  like Visual Studio or Microsoft Expression Blend without any loss of data.

Differences:

1.All XAML documents are also valid XML  documents, but the vice-versa case doesn’t hold true.

2.XML is a markup language whereas XAML is a  declarative application language.

3.XML finds its use primarily in web  applications in contrast to XAML which is used to design controls for Windows as  well as web applications.

Summary:

1.XAML is a declarative application language  that focuses on object definition, their properties, and their relationship  between one another.

2.XML is a markup language created by W3C that  is used to describe other markup languages.

3.XML is used in web publishing to create  interactive pages, for web searching, and to automate certain web tasks. It  finds use in e-commerce and helps in displaying information  on wireless devices and cellphones.

4.XAML is used to create, edit, and reuse GUIs  for Windows and certain web applications like Silverlight  plug-ins.

5.XAML is currently available for only the  Windows platform. It will be eventually moved to other platforms over a period  of time. XML is set to replace HTML because of its flexibility.
