Delphi Problems When Listing XML Sub-Node

Question

I have the code below, but at the node of [ICMS]. he puts it in anyway line I’m not getting to read the children. The same is happening with the [PIS] and [COFINS].* It does not obey level 2. How to pick up or check if there are more levels or knots? I thank anyone who can help...

procedure TForm1.Button1Click(Sender: TObject);

Answer 1

From what I understand you access the parent node that would be "", but only made a deal for his possible children.

When accessing the parent, you will need to loop it and create a condition for each of the children you want to access and so on.

It’s a somewhat stressful job, in my case I started working directly with String, reading the XML file and working and manipulating the string in XML to achieve the desired results, which saved a lot of development time.
