I have some Excel files with elements and attributes all of different values.
I would like to have Elements and attributes as column headings.  Where attributes are used as headings the element name should proceed the attribute name with an _ separating them.
The value of the element should have the element name followed by the word "value in the header as in AdminStatus_Value in the example below.

For example

<OrganizationId>4295856130</OrganizationId><AdminStatus effectiveFrom="2009-07-21T17:02:06">Published</AdminStatus><OrganizationName effectiveFrom="2005-08-18T04:00:00" organizationNameTypeCode="AKA" languageId="505062" organizationNameLocalNormalized="TX" sourceType="11" sourceLink="http://www.nyse.com/about/listed/tx.html" sourceUpdateDate="2012-04-03T07:22:36">TX</OrganizationName>

should have as headings:
OrganizationID,
AdminStatus_EffectiveFrom,
AdminStatusValue
OrganizationName_EffectiveFrom,
OrganizationName_organizationNameTypeCode,
OrganizationName_LanguageID,
OrganizationName_organizationNameLocalNormalized,
OrganizationName_SourceType
OrganizationName_SourceLink
OrganizationName_SourceUpdateDate

For guidance check this M$ link
I do not know the root element of your doco, but to access attributes use el.Attribute("effectiveFrom") or elements el.Element("OrganizationID"),
To save csv string use:
System.IO.File.WriteAllText("F:\\*******\\yourFilename.csv", csv);

For further help. we need an xml sample file to custom the link code but it should be straight forwards to code it.

Here is the first part of the file.

This is the code I'm using.  I get this error message
Object reference not set to an instance of an object.

using (StreamWriter sw = new StreamWriter("C:\\OAOrganization\\OrganizationNameParsed2.txt"))
                {
                    XElement custOrd = XElement.Load("C:\\OAOrganization\\OrganizationName.txt");
                    string csv =
                        (from el in custOrd.Element("Body").Elements("ContentItem").Elements("Data").Elements("Organization").Elements("OrganizationName")
                         select
                             String.Format("{0},{1},{2},{3},{4}",
                                 (string)el.Attribute("effectiveFrom"),
                                 (string)el.Element("effectiveTo"),
                                 (string)el.Element("organizationNameTypeCode"),
                                 (string)el.Element("languageId"),
                             //(string)el.Element("organizationNameLocalNormalized"),
                             //(string)el.Element("FullAddress").Element("Address"),
                             //(string)el.Element("FullAddress").Element("City"),
                             //(string)el.Element("FullAddress").Element("Region"),
                             //(string)el.Element("FullAddress").Element("PostalCode"),
                             //(string)el.Element("FullAddress").Element("Country"),
                                 Environment.NewLine
                             )
                        )
                        .Aggregate(
                            new StringBuilder(),
                            (sb, s) => sb.Append(s),
                            sb => sb.ToString()
                        );
                    sw.WriteLine(csv);


                }

Could you post a valid xml file (basically that contains a complete node or nodes of what you need)?

If the above is impossible then I have this code to put each element and attribute on a separate row.  The only thing is it gives the OrganizationID as published which is the value for AdminStatus.

Here is a sample code that reads your file and convert it to CSV string:
            XElement doc = XElement.Load(@"f:\temp\C--OAOrganization-File.xml");
            string csv = (from el in doc.Descendants()
                          let ns = String.Format("{{{0}}}",el.Name.NamespaceName)
                          where el.Name.LocalName == "Organization"
                          select String.Format("{0},{1},{2},{3}",
                          (string)el.Element(ns + "OrganizationId"),
                          (string)el.Element(ns + "AdminStatus").Attribute("effectiveFrom"),
                          (string)el.Element(ns + "AdminStatus"),
                          Environment.NewLine
                          )
                          )

The sample code contains how to read element value (OrganizationId) and an attribute value(effectiveFrom). It should be easy for you to add the extra info.
