[jQuery] Re: issue with ajax function

Well the reponseText property of the XHR object contains :

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">{"results": [
{
"id": "4",
"value": "guardian.co.uk"
}
]}</string>

that's what the webservice returns. Since dataType of my jquery ajax
method is set to 'json', this should be interpreted as json data.
