Have a look at the lazdocfrm.pas file located in lazarus/ide. for a
working example.


> Hello,
> I am trying to use the units XMLRead, XMLWrite, DOM to modify the
> structure of a XML file.
> Reading the XML file is very easy and works very well, but I am lost
> about how to modify it´s structure. Specifically I want to add a new
> "brother" to a node. I try to create a DomNode and then add it, but I
> cannot change the NodeName property. So how can I change the name of a
> newly created node??
> Also, how can I add a new Attribute to a DomNode??
> The following code will give an error because NodeName is read-only:
> var
>   NovoNo: TDomNode;
> begin
>     Posicao := TreeView1.Selected.Index;
>     NovoNo := TDomNode.Create(XMLDoc);
>     NovoNo.NodeName := 'categoria';
>     XMLDoc.DocumentElement.InsertBefore(NovoNo,
>      XMLDoc.DocumentElement.ChildNodes.Item[Posicao]);
> I looked at the examples on fpcsrc, but there are only very basic ones
> about xml.
> Any help e very welcome.
> thanks a lot,
