Copy xml element between documents

Question

Hello ,

I am trying to copy a xml element from one document to another but

I am facing to following exception :

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

This is my function:

   private void CopyElement(XmlDocument source,XmlDocument target,string elemId)
        {
            XmlNode nodeToCopy     =   source.ImportNode(source.GetElementById(elemId),true);
            XmlNode parentNode      =   target.GetElementById(nodeToCopy.Attributes["appendTo"].Value);
            parentNode.AppendChild(nodeToCopy);
        } 

Any help will be appreciated .

Kind regards,

Answer 1

you should do the import to the target. Something along the line:

 

   private void CopyElement(XmlDocument source,XmlDocument target,string elemId)
        {
            XmlNode nodeToCopy     =   target.ImportNode(source.GetElementById(elemId),true); // note: target
            XmlNode parentNode      =   target.GetElementById(nodeToCopy.Attributes["appendTo"].Value);
            parentNode.AppendChild(nodeToCopy);
        }

It's the target document that should import nodes. Your are actually importing node into the source document and the source document is the owner of nodeToCopy node.

 

To fix your problem, replace

XmlNode nodeToCopy   =  source.ImportNode(source.GetElementById(elemId),true);
 

by

XmlNode nodeToCopy   =  target.ImportNode(source.GetElementById(elemId),true);
