How to add root node to an XML File

HI ;

I have the following XML File

  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <SSISPackageLayout>

I want to add an root node like that

  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <SSISPackageInfoDesc>
     - <SSISPackageLayout>
- <SSSISPackageInfoDesc>

My question is how to add the   <SSISPackageInfoDesc> node to my existing xml using C#

Let's start with this: there is not an XML editing functionality in .net. Although can sound easy for your case, It would be very complex to manage in most cases.
What you basically do is to write a new file with the whole updated xml. There are 2 main ways to do it:
1) Load the entire xml into memory, add the desired node and write the whole document by overwritting the original file. This works well if xml file is small.
2) Load the xml contents, record by record, and write it into a new file, write the new node when pertinent and close the file.

Both ways are supported by .net. In the first case you can use an XmlDocument and in the second one you can use an XmlReader and XmlWriter. I suggest the first one.

Something like the attached code snippet.
XmlDocument oldDoc = new XmlDocument();

XmlDocument newDoc = new XmlDocument();
XmlElement root = newDoc.CreateElement("SSISPackageLayout");
newDoc.InsertAfter(root, null);

XmlNode content = newDoc.ImportNode(oldDoc.FirstChild, true);


Open in new window

Well, I'd consider just opening the file as text in C# and tabbing every line after adding what you want to the start/end (no special XML handling is needed for that operation).  It's a sloppy workaround, but it would be easy and quick to implement.
I'm not aware of a way to add a root node to an existing file that doesn't have one though using the XML classes (that doesn't mean one doesn't exist though, haha).
Good luck, and I hope you get a better answer to this one! :p
