wrong syntax in IE? - ajax & Js

Question

Hi, i have a code line like this: (JS)

numOfprocess = parseInt(xmlDoc.getElementsByTagName('process_count')[0].childNodes[0].nodeValue)
for (i = 1; i <= numOfProcess; i++)
{
processStatus = xmlDoc.getElementsByTagName('proccess' + i)[0];
if(processStatus.childNodes[0].nodeValue == false)
{...}
}

everytime i use this syntax there is an error "obejct required" while in Firefox eveything is ok. (the ... are just to explain)

i tried to do some debug like this:

alert(processStatus.childNodes[0].nodeValue) 

and the result was 0 so the var is fine. (also worked in ff so..)

the xml:

         <process_count>2</process_count>
         <Application_Status>
                        <proccess2>1</proccess2>
         </Application_Status>

another thing is that for i=1 it's ok but for i=2 not.

Thank you.

Indexing starts from 0, so if you have three items, their corresponding indexes are 0, 1 and 2, so you need to loop:

for (i = 1; i <  numOfProcess; i++)

instead of:

for (i = 0; i <= numOfProcess; i++)

EDIT:

You don't need a for loop to access your data, you can easily access required value via:

var processId = xmlDoc.getElementsByTagName('process_count')[0].childNodes[0].nodeValue;
var processStatus = xmlDoc.getElementsByTagName('process'+processId)[0].childNodes[0].nodeValue;

But, I suggest reconsidering your xml schema, since you need no more than one process status, why not doing simple thing like:

<application>
    <process id="2" status="1" />
</application>
