Software engineering notes

playing with e4x in firefox: iteratively appending xml elements

prereq: firefox w/ firebug installed
note: if there is no pre-existing 'child' element, using '+=' operator will append 'child' to 'parent', not 'children'
1) put this code in an html file
2) run it in firefox
3) look for output in console
var names = ['julio','juan','jose'],
	xml = <parent>
for(var i = 0; i < names.length; i++) {
    //check for pre-existing 'child'
	if(xml.children.child){//if there, append
	 	xml.children.child += <child name={names&#91;i&#93;}/>;
	}else{//create initial 'child' element
		xml.children.child = <child name={names&#91;i&#93;}/>;
