I did a study.
I was not exactly successful.
Sample:

Code

XMLReader = New XMLReader;
   
   Try
        XMLReader.OpenFile("string path file");
 
    Except

   EndTry;
   
   While XMLReader.Read() Do
      Try
         Message(XMLReader.AttributeName(0)+"-"+ XMLReader.AttributeValue(0));
      
      Except
      
      EndTry; 
   EndDo;

There are tables inside.
How can I read this?
I want to read and print the console as a message.
(Message (.....))

Code

XMLReader = New XMLReader;
XMLReader.OpenFile(nameFile);
While XMLReader.Read() Do
   //work
EndDo;

Code

For Each ElementCategory In DOMDocument.DocumentElement.ChildNodes Do
   Message(ElementCategory.GetAttribute("DESCRIPTION"));
   Message(ElementCategory.GetAttribute("CODE"));
   
   ElementsGRUP = ElementCategory.GetElementByTagName("GRUP");
   
   For Each ElementGRUP In ElementsGRUP Do
      Message(ElementGRUP.GetAttribute("DESCRIPTION"));
      Message(ElementGRUP.GetAttribute("CODE"));
      For Each ElementProduct In  ElementGRUP.GetElementByTagName("PRODUCT") Do
         Message(ElementProduct.GetAttribute("PRODUCTNAME"));
         Message(ElementProduct.GetElementByTagName("TAX")[0].TextContent);
      EndDo;
   EndDo;
EndDo;
