Id Collection

var orgId = (from x in xml.Descendants(xmlNamespace + "Included_by_Organizations").Elements()
                        select x into y
                        where y.Attribute(xmlNamespace + "type").Value == "Organization_Reference_ID"
                        select y.Value);

Setting values to object properties

var costCenterValues = from cc in xml.Descendants(xmlNamespace + "Report_Entry")
                                   select new CostCenter
                                   {
                                       CostCenterId = cc.Element(xmlNamespace + "Reference_ID").Value,
                                       Name = cc.Element(xmlNamespace + "name").Value,
                                       Code = cc.Element(xmlNamespace + "code").Value,
                                       //CostCenterHierarchyId = 
                                   };

            return costCenterValues.ToList();

Given the xml above what is the best way to set the CostCenterHierarchyID value? which is the The Organization_Reference_ID om the Included_by_Organizations xml collection. I'm able to get all the values from the var orgId but i'm not sure how to set the correct value for each record in costCenterValues - CostCenterHierarchyId.

Answer 1

Solution

.Element(xmlNamespace + "Included_by_Organizations")
.Elements(xmlNamespace + "ID")
.Where(x => x.Attribute(xmlNamespace + "type").Value == "Organization_Reference_ID")
.FirstOrDefault().Value.ToString()
