SGML is the basis XML and HTML and provides a way to define markup languages and sets the standard for their form.SGML passes structure and format rules to markup languages.

XML is a subset of SGML.It is a meta language and is used to define other markup languages.

What are XML attributes and elements? Explain with an example?

Manasa

Code
<person sex="female">
  <firstname>Anna</firstname>
  <lastname>Smith</lastname>
</person>
 
<person>
  <sex>female</sex>
  <firstname>Anna</firstname>
  <lastname>Smith</lastname>
</person>
 

In the first example sex is an attribute. In the last, sex is an element. Both examples provide the same information.

XML and HTML were designed with different goals: XML was designed to describe data and to focus on what data is. HTML was designed to display data and to focus on how data looks.That is HTML is about displaying information, while XML is about describing information.

HTML is static and you should use specific tags given by HTML and cannot use our own custom tags where as XML is dyanmic and we can create our own custom tags.

You can also create an XML file through the Java XML APIs and some simple Java.io File writer methods. Use the appendChild() method in the Node class for creating the tree structure of an XML. Use the FileWriter methods to save it into a file.

Rules for making a tag name are1.It should start with a letter or underscore(_)2.There are no reserved words , but however xml(in any case) should not be used as a tag name3.It can include digits, hyphen,periods, ':' can be used but best avoided because it is used for the namespace.
