XML

As-salam,

So we are going to introduce you about xml. Actualy we just know this topic yesterday. So we not know much about it. However we try our best to give a brief and understandable about XML.

So hope you all enjoy it.  smile~

XML was designed to transport and store data.

HTML was designed to display data.

It also means :

XML stands for EXtensible Markup Language.

XML is a markup language much like HTML.

XML was designed to carry data, not to display data.

XML tags are not predefined. You must define your own tags.

XML is designed to be self-descriptive.

XML is a W3C Recommendation.

XML actualy part of HTML. It is like HTML is a whole body. A Hands, ears, legs are XML.

Yet, both of it still have differences, which are :

1. XML is not a replacement for HTML.
2. XML was designed to transport and store data, with focus on what data is.
3. HTML was designed to display data, with focus on how data looks.

But, remember..

We need to get cautious when writing the coding because XML have a rule.

XML syntax rule:

• All XML Elements Must Have a Closing Tag.
• In HTML, you will often see elements that don't have a closing tag:                                           –<p>This is a paragraph<p>This is another paragraph.
• In XML, it is illegal to omit the closing tag. All elementsmusthave a closing tag:                           –<p>This is a paragraph</p><p>This is another paragraph</p>.

Now..

I will try to explain you all about XML Element and Attributes with the table below.

XML Element	XML Attributes
An XML element is everything from (including) the element's start tag to (including) the element's end tag.	XML elements can have attributes in the start tag, just like HTML.
An element can contain other elements, simple text or a mixture of both.	Attributes provide additional information about elements
Elements can also have attributes	Attributes are handy in HTML

This is example of XML Element and Attributes coding.

• In the first example sex is an attribute. In the last, sex is an element.
• Both examples provide the same information.
• There are no rules about when to use attributes and when to use elements.
• Attributes are handy in HTML.

So, if you need any detail about XML..You can visit http://en.wikipedia.org/wiki/XML.

Thank you for reading..

peace~
