Need to make XML generation code dynamic

Code:

//Takes input as values separated by ///
string csvString = "row11,row12,row13///row21,row22,row23///row31,row32,row33";

// Read into an array of strings.
string[] source = csvString.Split(new string[] { "///" }, StringSplitOptions.None);

//Generate XML based on the ',' and source array.
// Note that dbTemplate here is the comma separated template field values (check below)
XElement cust = new XElement("Root",
                    from str in source
                    let fields = str.Split(',')
                    select new XElement("Client",
                        new XElement(dbTemplate[0], fields[0]),
                        new XElement(dbTemplate[1], fields[1]),
                        new XElement(dbTemplate[2], fields[2])
                        )
                );


string result=cust.ToString();

Logic: I have got a table in SQL db having 2 columns: IssueType and template and written code to fetch the template based on IssueType .

IssueType      Template
Client    Name,Phone,Address
Claim     Name,Type,Date,HandlerName,SettledDate
Incident  Place,Cost,Name,Date

Above code generates XML output for 3 fixed csv values and corresponding 3 fixed IssueType->Tempalte values (ie:IssueType=Client). I want to make the code dynamic (Presently it will only work for IssueType=Client ie:having 3 template values). The no. of values in comma separated CSV will always be equal to the number of comma separated values coming from respective IssueType column from db. Please guide.
