Replace OuterXml OR generate intended string from InnerXml

I have a UI that uses the DataGridView to display the content of XML files.

If XmlNode contains only InnerText, it's quite simple, however I'm having a problem with nodes that contains childnodes (and not only string).

Simple

<node>value</node>

Displayed as "value" in DataGridViewCell.

Complex

<node>
    <foo>bar</foo>
    <foo2>bar</foo2>
</node>

The problem is that the InnerXml code is not intended and it's very hard to modify in UI.

I've tried to use XmlTextWriter to "beautify" the string - it works quite well, however requires a XmlNode (includes node, not only childnodes) and I cannot assign it back to InnerXml.

I would like to either see following in the UI: 

<foo>bar</foo>
<foo2>bar</foo2>

(this can be assigned to InnerXml afterwards)

Or 

<node>
    <foo>bar</foo>
    <foo2>bar</foo2>
</node>

(and find a way how to replace OuterXml with this string).

Thanks for any ideas, Martin

You can load the OuterXml to XElement, then use String.Join() to join all child elements of the root node (in other point-of-view, the InnerXml) separated by line break, for example :

XElement e = e.Parse(something.OuterXml);
var result = string.Join(
                          Environment.NewLine, 
                          e.Elements().Select(o => o.ToString())
                        );
