Hi mkarthik415;

If you are using Visual Studio 2008 with SP1 installed then you can use Linq to XML to do what you need as seen in the following code snippet.

XDocument xdoc1 = XDocument.Load("C:/Working Directory/FirstDoc.xml");
XDocument xdoc2 = XDocument.Load("C:/Working Directory/SecondDoc.xml");

xdoc1.Root.Add(xdoc2.Root.Descendants());

Open in new window

Hi mkarthik415;

Of course if you want to safe the new document to the file system you would then do the following:

xdoc1.Save("File path and name as a string parameter");

You do realise that that result is actually invalid XML, right? XML does not permit two root nodes in one document.

Hi kaufmed;

I assumed that he did not display the root nodes and just the inner nodes. But that may be a wrong assumption.

"XML does not permit two root nodes in one document" answers my question. Is it possible to have multiple root elements in any  xml.net classes.

Thank You.
