XML ReplaceChild

[rekam]

Hello!

 

I need some help to use the method ReplaceChild. What I know is the structure of it.

 

domDoc.ReplaceChild( newChild, oldChild )

 

The problem I have is that the new child is not from the same dom document as the old child. The thing is, I don't understand why the two of them must be from the same file.

 

It's not very logical...:confused: I mean, I have a node in a document. If I want to replace it, the new node will be *in any case* a node that is not in the file, I think...

 

Well, I'm a bit confused about that. But I abolutely need this method, and I can't have the two nodes coming from the same document, sob...

 

If someone has an idea...thanks a LOT !

Here's a part of my code...The error is : "The node to be removed is not a child of this node"...

       Dim fDom As New XmlDocument
       fDom.Load(Me.fileName)
       Dim paramDefault As XmlElement
       Dim oldParam As XmlNode

       'This method returns a XmlElement type. It puts in paramDefault some children and some values. The fDom is passed by reference.
       paramDefault = Me.SetParamDefault(fDom)
       'Then we select the old node from the document. Game is the root element.
       oldParam = fDom.SelectSingleNode("game/paramDefault")
       'Here's the error...
       fDom.ReplaceChild(paramDefault, oldParam)
       fDom.Save(fichierTemp)

 

I use the SetParamDefault method in other method and function in my class, and it works perfectely...

 

Maybe I'm wrong, but it seems everything 's right..

I believe I see the problem. The only child node of fDom is the

"game" node; thus, the "game/paramDefault" node is not a child

of the fDom document, it's a child of the "game" node. You need

to call the ReplaceChild of the "game" node instead of the

ReplaceChild method of the main document.

 

'Here's the error...
fDom.SelectSingleNode("game").ReplaceChild(paramDefault, oldParam)
