Something that I haven’t noticed for a long time are dynamic xml definitions. What it is; Its a very easy way to construct xml with dynamic content. Here is a short example:

var nodeValue:String = "bis naii";
var attributeValue:String = "mich";
var xml:XML = <speech speaker={attributeValue}>{nodeValue}</speech>;
trace( xml ); // <speech speaker="mich">bis naii</speech>

The {} braces are replaced by the variable value. You can also place more complex stuff inside these curly braces. Here is another example:

var xml:XML = <root />
for ( var i:Number = 0; i < 3; i++ ) {
    xml.appendChild( <child>{"content: " + ( i + 1 )}</child> );
}
/**
 * gives:
 * <root>
 * <child>content: 1</child>
 * <child>content: 2</child>
 * <child>content: 3</child>
 * </root>
 */

In some situations this way of constructing an xml structure is very practical….
