Note Submitter: mcgooogletz at gmail dot com ---- xml notes: <tag one="one"/> <tag two="two"/> <tag three="three/> -tags can be read as arrays (their text nodes) BUT multiple attributes means accessing them one at a time. i.e.: <thing1 length="2" width="4" height="4/> thing1["length"] // thing1["width"] // thing1["height"]// -don't even think about this: thing1["length"]["width"]["height"]; // you have to do them one at a time. -it's for your own good. //something to look out for.. <thing1 length="2" width="4" height="4/> <thing1 length="3" width="4" height="4/> can't do this: thing1[0]["length"]; //so very wrong. -however foreach looping might solve it. ->psuedo code below. foreach ($thing1 as $a){ $a["length"] // $a["width"] // $a["height"]// } ----------------------------------------- last note: -analogy. //exhibit a: inefficiency with tags..-good for text storage- large chunks of raw data like news articles.. (char)$var="blue"; <var>blue</var> //exhibit b: efficient attribute implementation (good for data heavy filing (i.e.. like storing a multitude of values (think like exporting images and such)) $var2=array($one,$two,$three, $four=array($haha, $what_now=array($huh, $oh, $oops) ) ); <var2 one='' two='' three=''> <four haha=''> <what_now huh='' oh='' oops=''/> </four> </var2> -be smart with your attributes and make psuedo structures with them as opposed to riddling the doc with more text node tags than data :).
