As3 xml node change/replace/delete

[TrueSign]

Hi,

Im working with piece of code that creates dynamically xml and send it to DB.

var _round:XML;

_round = new XML(<round/>);

_round.@num = currentRound;

var answer:XML = <answer/>;

answer.@num = 0;

trial.appendChild(_round);

In some cases I appendChild like that:

     xml.level.appendChild(_round);

this is in a situation when _round xml is not in a xml.level already

but what if I would like to delete that exisiting round node and put another new one in that place? what Should i do? I tried:

delete xml.level.round; //then append new _round

or

for each (var round:XML in xml.level) {

      round.replace(round.childIndex(), _round);

}

None of this works. Few other wierd errors appears when I have tried to delete that node or replace it.

What is a best way to do it? thanks

what's trial?  what xmlLevel?

do you mean you have something like:

var xmlLevel:XML;

xmlLevel = new XML(<level/>);

var answer0:XML = <answer/>;

answer0.@num = 0;

var currentRound:int = 1;

var _round1:XML;

_round1 = new XML(<round/>);

_round1.@num = currentRound;

_round1.appendChild(answer0);

currentRound = 2;

var answer1:XML = <answer/>;

answer1.@num = 1;

var _round2:XML;

_round2 = new XML(<round/>);

_round2.@num = currentRound;

_round2.appendChild(answer1);

xmlLevel.appendChild(_round1);

xmlLevel.appendChild(_round2);

and there's an update to currentRound=2:

currentRound = 2;

var answer2:XML = <answer/>;

answer2.@num = 22;

and you want to update xmlLevel round 2 with the most recent answer?  if yes, use:

xmlLevel.round.(@num==2).replace("answer",answer2);

I din't want to copy a long code there, so my mistake.

Basically I appended few other xml elements to round like for example, answer, trial and few others. So round it's complex dynamic xml.

Yes. Someting like that.

I used your : xmlLevel.round.(@num==2).replace("answer",answer2);

and I found a bug somewhere else. Anyway, it's fixed now. Thanks
