TForm1 = class(TForm)

end;
var

implementation
{$R *.dfm}
procedure TForm1.btn1Click(Sender: TObject);
var
noderef: IXMLDOMNodeRef;
root: IXMLDOMNode;
Node: IXMLDOMNode;
begin
XMLDocument1.LoadFromFile('test.xml');
XMLDocument1.Active := True;
noderef := XMLDocument1.DocumentElement.DOMNode as IXMLDOMNodeRef;
root := noderef.GetXMLDOMNode; // 获取跟节点
Node := root.selectSingleNode('ItemList/Item[@name="name2"]'); // 根据路径的属性值获取节点
ShowMessage(Node.Attributes.getnameditem('title').Text); // title2
Node.Attributes.getnameditem('title').Text:='hello'; // <Item name="name2" title="title2"/> => <Item name="name2" title="hello"/>
XMLDocument1.SaveToFile('test.xml');
end;
end.
test.xml文档:
<?xml version="1.0" encoding="utf-8"?>
<Test>
<ItemList>
<Item name="name1" title="title1"></Item>
<Item name="name2" title="title2"/>
</ItemList>
</Test>
