private void MakeInsertes(IDataSource ds, XmlDocument xml) {
XmlNodeList insertingRecords = xml.SelectNodes("records/Created/record");
string id = GetIdColumnName();
foreach (XmlNode node in insertingRecords)
{
record = node;
values = new SortedList(this.Reader.Reader.Fields.Count);
keys = new SortedList();
oldValues = new SortedList();
foreach (RecordField field in this.Reader.Reader.Fields)
{
//modify by neo date:2011/6/9 emptystring convert to null
XmlNode keyNode = node.SelectSingleNode(field.Name);
if (String.IsNullOrEmpty(keyNode.InnerText))
values[field.Name] = null;
else
values[field.Name] = keyNode != null ? keyNode.InnerText : null;
}
