convert xml file to csv

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.

This is the code I'm using.  I get this error message

using (StreamWriter sw = new StreamWriter("C:\\OAOrganization\\OrganizationNameParsed2.txt"))

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

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:
