Getting XML data from the string

string xml = "<ABCProperties> <Action> Yes | No | None </Action><Content>
<Header> Header Text </Header><Body1> Body Paragraph 1 </Body1>
<BodyN> Body Paragraph N</BodyN></Content><IsTrue> true | false </IsTrue>
<Duration> Long | Short </Duration></ABCProperties>";

Here, from the XML, I want to extract certain strings. First is the Header Text in the Header tags.

When, I try 

XDocument doc = XDocument.Parse(xml);
var a = doc.Descendants("Header").Single();

I get variable a = <Header> Header Text </Header>. How can I get only var a = Header Text?

Secondly, I want to get text of all the Body paragrahs. It can be either Body1, Body2 or BodyN. How can I get contents of all Body tags.

Can anyone help me with this?

Start with just getting the content node, which is what you really want, and then iterate through its children checking if it's a body or header node, and use the string.Trim() function to get rid of leading/trailing whitespace.:

string xml = @"<ABCProperties> <Action> Yes | No | None </Action><Content>
<Header> Header Text </Header><Body1> Body Paragraph 1 </Body1>
<BodyN> Body Paragraph N</BodyN></Content><IsTrue> true | false </IsTrue>
<Duration> Long | Short </Duration></ABCProperties>";

XDocument doc = XDocument.Parse(xml);

XElement content = doc.Root.Element("Content");

foreach (XElement el in content.Elements())
{
    string localName = el.Name.LocalName;

    if (localName == "Header")
    {
        Console.WriteLine(localName + ": " + el.Value.Trim());
    }
    else if (localName.StartsWith("Body"))
    {
        Console.WriteLine(localName + ": " + el.Value.Trim());
    }
}

Console.ReadKey();

You're asking for the Header element - so that's what it gives you. If you only want the text of that, you can just use:

var headerText = doc.Descendants("Header").Single().Value;

To find all the body tags, just use a Where clause:

var bodyText = doc.Descendants()
                  .Where(x => x.Name.LocalName.StartsWith("Body"))
                  .Select(x => x.Value);
