[1760]C oncept of Qualified Names
By Sandeep Seshan on 2006/05/26 07:29:48  Rate
The QName class encapsulates the concept of "Qualified Names" in an XML NameSpace. 
 A Qualified Name looks like this :- 
  
  
 prefix : localpart 
  
  
 E.g.: 
  
  
 xmlns:test 
  
  
 The prefix makes the name of an XML Element or an XML Attribute as "Qualified" -  
 the prefix itself is just a " pointer " to the name of the NameSpace, which is a  
 URI  (  all the Geeky stuff simply translates to " declare the prefix in the beginning 
 of the XXML Document and let it point to some URI "  ) . 
  
  
 E.g: 
  
  
  < test:A 
      xmlns:test = "http://someur1.com" 
  >  
     < test:B >  200  < /test:B >  
  < /test:A >  
       
 It's easly to see that the URI may contain characters that may not be valid in an XML Document. 
 Hence, you may use a prefix.
