A Basic XML Composition Utilizing Attributes
Hello there, I am Dennis Kaye. Introducing my '5 minute XML' series where by I deliver regular bite size tutorials.
The current subject is for people of you who are actually completely new to XML.
The up coming example displays a simple well formed XML file. It can easily be entered utilising a uncomplicated text editor or maybe any kind of of the XML editors now on the market. Whenever you are writing the document away the file-name should really finish with a .xml.
[human gender="male" born="18 July 1990"]
[hairColour]
Blonde
[/hairColour]
[/human]
Typically the above [human] ... [/human] element has basically one other child element now. This time, the information retained in gender and born is actually made accessible utilizing attributes rather than of 'child elements'. Typically the order of the attributes doesn't matter however each should take the form attr="stuff", following the [elem] tag.
In the instance a good deal more than one attribute is employed, these have to be divided by whitespace and also each attribute needs to be unique for any one element. From this point people might possibly well ask, when should anyone place content inside an attribute as opposed to a child element? Certainly the response to this is not quite so clear as you would possibly suppose.
A number of groups think attributes are metadata related to the element, although elements really are for the information itself nonetheless you'll find it certainly not routinely apparent which is which I might encourage you to seek the advice of further resources advice, further than which common sense could overcome.
A plethora of information is available on XML just for those people who may like to know much more. For the definitive guide, visit www.W3.org.
