First I add code and External Assemblies to the .NET GLobal section of the Mapping tab:
using System;
using System.Collections.Generic;
using System.Xml;
XmlDocument demographicsXML = new XmlDocument();
XmlNodeList nodes;
External Assemblies: System.dll,,System.Xml.dll,System.Data.dll
Second I populate the global variables using a Repeat Each Row Before Operation:
using System;
using System.Collections.Generic;
using System.Xml;
void CSharpProcedure()
{
string demographicsString = "<Demographics>"+Starfish.OriginData["DEMOGRAPHICS"].ToString()+"</Demographics>";
demographicsXML.LoadXml(demographicsString);
nodes = demographicsXML.DocumentElement.SelectNodes("/Demographics");
}
Third, I populate a field with data from the global variable:
object ScriptedField()
{
string res = "";
foreach (XmlNode node in nodes)
{
res = node["EXTITLE"].InnerText;
}
return res;
}
