Question

SELECT
    CAST ([content_html] AS XML).query(\'/root/Physicians/specialty/a\') AS [Specialty1]
    , CAST ([content_html] AS XML).query(\'/root/Physicians/specialty2/a\         


        

Answer 1

You can add something like this to the code behind of the page:

protected object MyEval(string expression)
{
    object o = null;
    try
    {
        o = DataBinder.Eval(this.GetDataItem(), expression);
    }
    catch
    {
        o = System.String.Empty;
    }
    return o;
}

and then replace all Evals with "MyEval":

<%# MyEval("Specialty1").ToString() + DisplayMultiplMyEvalues(MyEval("Specialty2").ToString()) + DisplayMultiplMyEvalues(MyEval("Specialty3").ToString()) + DisplayMultiplMyEvalues(MyEval("Specialty4").ToString()) + DisplayMultiplMyEvalues(MyEval("Specialty5").ToString()) + DisplayMultiplMyEvalues(MyEval("Specialty6").ToString()) %>
