how can i perse and populate multiple data in combobox by ajax

responseText should be in the format "( apple||orange||Mango|| )"


returnElements=http_request.responseText.split("|| ")

document.getElementById('form_loan_officer').optio ns[j] = new Option('Select Loan Officer','');
for ( var i=1; i<returnElements.length-1; i=i+2)
{
j++;
valueLabelPair = returnElements[i];
document.getElementById('form_loan_officer').optio ns[j] = new Option(returnElements[i+1], returnElements[i]);
}


better generate a xml file and parse.
