Getting exception "The node to be inserted is from a different document context."

[Eirik M.]

Hi,

I've got the following piece of code that's causing me a bit of a problem

XmlDocument doc = new XmlDocument ();
XmlNode rootNode = doc.CreateNode (XmlNodeType.El ement, "usersettin gs",
null);
User user = new User (userid);
XmlNode rolesNode = user.GetRoles ();
rootNode.Append Child (rolesNode);
:
:

The last line (rootNode.Appen dChild (rolesNode)) throws an exception "The
node to be inserted is from a different document context." How can I work
around this? The code above is from a Web-service that collects various
information regarding a user from different sources each of which returns an
XmlNode. The web-service adds each XmlNode to a "root" node and then returns
this "root" node to the client.

The proble you're having relates to the fact that the user object is
creating a node from othe document, rather than from doc.

Either you pass doc to GetRoles so that the nodes are created from the
correct instance, or you may have to use ImportNode

rootNode.Append Child(doc.Impor tNode(rolesNode ,true));

instead of the previous AppendChild.

Nah, don't wan't to pass it around.

Did the trick!

instead of the previous AppendChild.
