I have the following code, but I am not able to list the node name and its value. I can search and show the main node [ide] but the sub-node that would be [cUF] + value this I can not.

procedure TForm1.Button3Click(Sender: TObject);  
var
    Doc: IXMLDOMDocument;  
    Element: IXMLDOMElement;  
    List: IXMLDOMNodeList;  
    attrib : IXMLDOMNode;  
    Path,ID,title,producer: string;  
    i: integer;  
begin    
    Memo1.Lines.Clear;
    Doc := CoDOMDocument.Create;
    Doc.load(ArquivoXML);
    // Element := Doc.documentElement;
    // List := Element.getElementsByTagName('ide');
    for i := 0 to Doc.selectNodes('//ide').length do
    begin
        Memo1.Lines.Add(Doc.selectNodes('//ide').item[i].baseName);     // Nó onde está parado
        Memo1.Lines.Add(Doc.selectNodes('//ide').item[i].Get_nodeName); // = basename
        Memo1.Lines.Add(Doc.selectNodes('//ide').item[i].nodeName);     // = basename
        Memo1.Lines.Add(Doc.selectNodes('//ide').item[i].selectSingleNode('cUF').text);   // Pego o Conteúdo do item do Nó
        Memo1.Lines.Add(Doc.selectNodes('//ide').item[i].selectSingleNode('cNF').text);   // Pego o Conteúdo do item do Nó

//        Memo1.Lines.Add(IntToStr(GetNodeInt(attrib,'cNF')));
    end;
end;

Apparently the length property of IXMLDOMNodeList is not working properly. The solution was then to use the nextNode function until it returns nil . After getting the node just scan all child nodes and print them:

procedure TForm1.Button3Click(Sender: TObject);
var
    Doc: IXMLDOMDocument;
    nodes: IXMLDOMNodeList;
    node : IXMLDOMNode;
    i: integer;
begin
    Memo1.Lines.Clear;
    Doc := CoDOMDocument.Create;
    Doc.loadXML(
      '<CFe>                                                                                      ' +

    );

    nodes := Doc.getElementsByTagName('ide');

    repeat
      node := nodes.nextNode;

      if (node = nil) then
        Break;

      Memo1.Lines.Add(node.baseName);
      for i := 0 to node.childNodes.length - 1 do
        Memo1.Lines.Add('[' + node.childNodes.item[i].nodeName + '] ' + node.childNodes.item[i].text);
    until (node = nil);
end;

The result of this was:

I do not have Delphi 5 installed on my machine, I ran those tests in Delphi 2010, but I do not think there are many differences. It also could not load XML with tags involved by [] instead of <> .
