Simple XML array node target problem... Newbie

I am having a problem selecting only the first node value from this xml tree "xx" no matter how many dev items returned from array 2 or 200. I have been able to select the first item but I get hung up writing an array. New to actionsript learning is school, I spent time searching the board, if this is posted elsewhere please refer.

This is the target to find all first nodes only from an array that I am using. I know it is incorrect.
ArrValue[i] = BaseNode.FirstNode.childNodes[i]


Thanks for any guidance.

Code:

---

<?xml version="1.0"  encoding="ISO-8859-1"?>
<data>
<dev label="Sep 03" >
        <xx>76084.71</xx>
        <ww>52946.77</ww>
        <ee>64058.4</ee>
</dev>
<dev label="Sep 04" >
        <xx>117638.69</xx>
        <ww>72082.64</ww>
        <ee>94867.35</ee>
</dev>
</data


ACTIONSCRIPT-----------------------


function LoadSchoolData() {
  var BaseNode = thisXML.childNodes[0];
 
 
  //set up arrays
  var ArrLabel = new Array();
  var ArrValue = new Array();       
  var ThisNode;
 
 
  //create datasource
  var SchoolData = new DataProviderClass();
 
 
  //get Data
  for (var i=0; i >< BaseNode.childNodes.length; i++) {
      ThisNode = BaseNode.childNodes[i];
      ArrLabel[i] = ThisNode.attributes["label"];
     
    /* I am having a problem with the ArrValue[i] selecting all the "<xx>76084.71</xx>"  node from the tree from an array  no matter if it is 1 or 100.*/
     
      ArrValue[i] = BaseNode.FirstNode.childNodes[i];
      SchoolData.addItem({CW:ArrLabel[i], TB:ArrValue[i]});
  }
  MyDev.setDataProvider(SchoolData);
  MyDev.setLabelSource("CW");
  MyDev.setValueSource("TB");

}

set up a 2D array to hold the dev items

PHP Code:

---

function LoadSchoolData() {
   var BaseNode = thisXML.childNodes[0];
   var ArrLabel = new Array();
   var ArrValue = new Array();    
   var ThisNode;

   for (var i=0; i<BaseNode.childNodes.length; i++) {
    ThisNode = BaseNode.childNodes[i]; 
    len2 = ThisNode.childNodes.length; 
    ArrLabel[i] = ThisNode.attributes["label"];
    ArrValue[i] = new Array();
    for (var ii=0; ii<len2; ii++) {
    ArrValue[i][ii] = ThisNode.childNodes[ii].firstChild;
    trace("ArrValue["+i+"]["+ii+"] "+ArrValue[i][ii])
    }
    }
};

hth :)

I will continue to explore so one day I can give back to the board.

Thanks. This works well.

you're welcome :thumbsup:

Good Hunting :D

I thought I had this school project solved, but when I examined the output, it seems that I must

be still doing something wrong. It still picks up unwanted data/nodes. I only need the first node <eb> values to plot not any of the other values. The xml tree cannot change. Any help would be appreciated.

XML and actionscript below.

cannot open Flash 9 files here

can you use removeTreeNodeAt(index)
or the Flash 9 equivalent code ?

a_modified_dog thanks for your help again. I finally solved my issue.

I targeted my node using this path.

ArrValue[i] = this.firstChild.childNodes[i].childNodes[0].firstChild.nodeValue;

Now I am able to select the first node only.

I do appreciate your reply.
