designing XML with large data sets for ActionScript3

Question

I have a very large XML file which has like 40000 data, and when I try to load the XML using Actionscript3, and then populate the data into an Array, I get the following Error:

A script has executed for longer than the default timeout period of 15 seconds.

Is there a way to bypass this timeout issue? Here is the sample XML

<Map>
   <Data>0</Data>
   <Data>1</Data>
   <Data>2</Data>
   <Data>3</Data>
    // continue for many many times
   <Data>39999</Data>
</Map>

The line break seems to be at the for loop. The code is like this

var aNumberArray:Array = new Array( 200 * 200 );
var nRowIndex:int = 0;
for ( ; 200 > nRowIndex; ++nRowIndex ) {
    var nColumnIndex:int = 0;
    for ( ; 200 > nColumnIndex; ++nColumnIndex ) {
        var nIndex:int = nColumnIndex + nRowIndex * 200;
        // assume cXMLMap is already a pre read XML class
        aNumberArray[ nIndex ] = new int( cXMLMap.Data[ nIndex ] );
    }
}

I am suspecting that the cXMLMap.Data[ nIndex ] is taking alot of time to get the variable from the XML. Please advice.

Answer 1

I found the answer, I need to change the format of the XML to something like below

// given a data set of 200 X 200 fields
<Map>
    <Data>00 10 20 30 40 ..... 1990</Data>
    <Data>00 11 21 31 41 ..... 1991</Data>
    // repeat until reach 200 times
    <Data>2000 2001 2002 2003 2004 ..... 199200</Data>
</Map>

This will reduce the XML parsing duration, however, I need to write code to tokenize the string in actionscript3.
