These small samples shows how you can write code work with EPT document from a Content Studio Web page.

Read an EPT field

This code works in presentation templates only. The code uses the CS_DataFields property that returns an EPTXmlTextParser object. If used outside a presentation template CS_DataFields is null (Nothing in Visual Basic).

C# 
 if(CS_DataFields != null)
 {
    //Read the value of a EPT data field named Title
    string theString = "";
    //first check if the field really exists. 
    if(CS_DataFields.ExistsField("Title"))
    {
       theString = CS_DataFields["Title"];
       //Write out the value
       Response.Write(Server.HtmlEncode(theString));
    }
 }
VB.NET 
If Not CS_DataFields Is Nothing Then
   'Read the value of a EPT data field named Title
   'first check if the field really exists. 
   Dim theString As String = ""
   If CS_DataFields.ExistsField("Title") Then
      theString = CS_DataFields("Title")
      'Write out the value
      Response.Write(Server.HtmlEncode(theString))
   End If
End If

Read an EPT field with an EPT document identifier


This code works in any Content Studio document. The code uses the CS_GetAnyEPTDocument method that returns an EPTXmlTextParser object. An exception is thrown if the document does not exist. The sample reads a document and enumerates all the fields and writes out their names and valuesC# 
int documentID = 4372;
ContentStudio.Document.EPT.EPTXmlTextParser ept;
Response.Write("<dl>");
try
{
      //Get the EPT document
      ept = CS_GetAnyEPTDocument(documentID);
      foreach(string fieldName in ept)
      {
         Response.Write("<dt>" + fieldName + </dt>);
         Response.Write("<dd>");
         //Check if the field is empty or null
         if(!ept.IsEmptyField(fieldName))
             Response.Write(Server.HtmlEncode(ept[fieldName]));
         else
             Response.Write("The value is empty or unspecified");
         Response.Write("</dd>");
      }
}
catch(ContentStudio.CSException ex)
{
   Response.Write("<dt>" + Server.HtmlEncode(CS_TranslateMessage(ex)) + "</dt>");
}
catch(Exception ex)
{
   Response.Write("<dt>" + Server.HtmlEncode(ex.Message) + "</dt>");
}
Response.Write("</dl>");
VB.NET 
Dim documentID As Integer = 4372
Dim ept As ContentStudio.Document.EPT.EPTXmlTextParser
Response.Write("<dl>")
Try
      'Get the EPT document
      ept = CS_GetAnyEPTDocument(documentID)
      For Each fieldName As String In ept
         Response.Write("<dt>" & fieldName & </dt>)
         Response.Write("<dd>")
         'Check if the field is empty or null
         If(Not ept.IsEmptyField(fieldName))
             Response.Write(Server.HtmlEncode(ept(fieldName)))
         Else
             Response.Write("The value is empty or unspecified")
	End If
         Response.Write("</dd>")
      Next
Catch ex As ContentStudio.CSException
   Response.Write("<dt>" & Server.HtmlEncode(CS_TranslateMessage(ex)) & "</dt>")
Catch ex As Exception
   Response.Write("<dt>" & Server.HtmlEncode(ex.Message) & "</dt>")
End Try
Response.Write("</dl>")
