Quickstart With XML: Part 3

• All XML must have a root element.
  
  Example
  
  1. <roots>
  2. <name>Shresth Jaiswal</ name>
  3. <date of birth>2nd October 1999</ date of birth>
  4. </root>
• All the tags in XML must be closed.
  
  Example
  
  1. </root>
• All tags must be properly nested.
  
  Example
  
  Wrong:
  
  1. <P><Q>Hello</P></Q>
  2. <s><t>Hello</s></t>
  Right:
  
  1. <P><Q>Hello</Q></P>
  2. <s><t>Hello</t></s>
• All the names of XML tags have strict limits.
  
  Example
  
  Wrong:
  
  1. <01_author>
  2. <”author”>
  Right:
  
  1. <author>
  2. <_author>
• Tags in XML are case-sensitive.
  
  Example
  
  Wrong:
  
  1. <root>Shresth</Root>
  2. <xml>first page</Xml>
  Right:
  
  1. <root>Shresth</root>
  2. <Xml>first page</Xml>
• In XML tags, names cannot contain spaces.
  
  Example
  
  1. </NAME>
• In XML, attribute values must appear within quotes.
  
  Example
  
  Wrong
  
  1. <note date= 18/05/2015>
  2. </note>
  3. Right
  4. <note date= ‘’18/05/2015”>
  5. </note>
