A Straightforward XML Composition Applying Attributes

The current theme is just for individuals of you who are new to XML.

The below case in point displays a effortless well formed XML file. It can certainly be entered utilizing a uncomplicated text editor or maybe just about any of the XML editor now readily available. Whenever you are producing the document away the file-name will need to finish with a .xml.

<human gender="male" born="18 July 1990">

 <hairColour>

 Blonde

    </hairColour>

</human>

Typically the above <human> ... </human> element comprises just one other child element now. This occasion, the particular information retained in gender and born is made accessible making use of xml schema attributes rather than of 'child elements'. Typically the arrangement of the attributes is not going to matter yet each need to take the form attr="stuff", right after the <elem> tag.

Where much more than one attribute is used, these must be separated by whitespace and each and every attribute have to be unique with regard to any one element. Around this point people may well ask, when should one place content within an attribute instread of a child element? To be honest the response to this is not quite so clear as you might think.

Several groups think attributes are metadata about the element, although elements are actually for the information itself although it's not necessarily usually noticeable which in turn is which I'd personally encourage you to check with further resources advice, more than which common sense might overcome.
