XML Tutorial/Introduction/Attribute

An attribute creates additional information without adding text to the element.

   <source lang="xml">

<animal>

 <name language="English">T1</name>
 <name language="Latin">T2</name>
 <project>project1</project>
 <weight>3 points</weight>

</animal> Attribute names must follow the same rules as for valid element names. If a value contains double quotes, use single quotes to contain the value (and vice versa). An attribute may not contain a reference to an external entity. An attribute may not contain the symbol <, use < to represent it.</source>

Attributes are simple name/value pairs associated with an element

   <source lang="xml">

You can"t have more than one attribute with the same name on an element. Order of attributes is not relevant. They are attached to the start-tag, but not to the end-tag. <name nickname="007">

   <first>Bond</first> 
   <last>James</last> 

</name> Attributes must have values. Those values must be in quotes. Either single quotes or double quotes are fine, but they have to match. <input checked="true"> or <input checked="true"></source>
