Hi All,

I am trying to fetch more than 5k records using fetch xml from CRM using web api.

I am experiencing the below error. Can anyone assist me where i am doing wrong.

System.AggregateException: One or more errors occurred. (Malformed XML in the Paging Cookie)
---> CoreAPI.CRM.Classes.ServiceException: Malformed XML in the Paging Cookie

I am using this code to fetch second request in CRM

if (response.Contains("@Microsoft.Dynamics.CRM.fetchxmlpagingcookie"))
{

var myDtoObject = JsonConvert.DeserializeObject<GenericDto<Account>>(response);
XmlDocument doc = new XmlDocument();
doc.LoadXml(myDtoObject.Cookie);
XmlElement root = doc.DocumentElement;
pagingCookie = root.Attributes["pagingcookie"].Value;
string s = root.Attributes["pagingcookie"].Value;
pagingCookie = GetDecodedCookie(s);

//calling the request with incre pagenumber and pagingcookie

}

Hi SHG,

If it's possible please put the paging cookie data so that we can analyze.

There could be data having special characters like "&". You can take the paging cookie value and decode it to see if the XML is generated without any issue.
