Follow the code:

// Leitura Dados Itens da Nota Fiscal...
xmlNCab := NoPrinc.ChildNodes.FindNode('det');
while not (xmlNCab = Nil) do
begin
    inc(l);
    sgProds.RowCount := l;
    //xmlNCab.ChildNodes.FindNode('det');
    xmlNItm := xmlNCab.ChildNodes['prod'];

    cProd := xmlNItm.ChildNodes['cProd'  ].Text; // Código do produto CFOP
    xProd := xmlNItm.ChildNodes['xProd'  ].Text; // Nome do produto
    uCom := xmlNItm.ChildNodes['uCom'    ].Text; // Sigla unidade da embalagem
    qCom := xmlNItm.ChildNodes['qCom'    ].Text; // Quantidade do produto (4dec,S/M)
    vUnCom := xmlNItm.ChildNodes['vUnCom'].Text; // Valor unitário do produto (4dec,S/M)
    vProd := xmlNItm.ChildNodes['vProd'  ].Text; // Valor total do produto (2dec,S/M)

    sgProds.Cells[0,l] := cProd;
    sgProds.Cells[1,l] := xProd;
    sgProds.Cells[2,l] := uCom;
    sgProds.Cells[3,l] := qCom;
    sgProds.Cells[4,l] := vUnCom;
    sgProds.Cells[5,l] := vProd;

    DataModule1.zqInsertXML.Close;
    DataModule1.zqInsertXML.SQL.Clear;
    DataModule1.zqInsertXML.SQL.Add('INSERT INTO xmlprod(cProd, xProd, uCom, qCom, ' + 'vUnCom, vProd, chval)');
    DataModule1.zqInsertXML.SQL.Add('VALUES (:pcProd, :pxProd, :puCom, :pqCom, ' + ':pvUnCom, :pvProd, :pchval)');
    DataModule1.zqInsertXML.ParamByName('pcProd').AsString := cProd;
    DataModule1.zqInsertXML.ParamByName('pxProd').AsString := xProd;
    DataModule1.zqInsertXML.ParamByName('puCom').AsString := uCom;
    DataModule1.zqInsertXML.ParamByName('pqCom').AsString := qCom;
    DataModule1.zqInsertXML.ParamByName('pvUnCom').AsString := Trcpv(vUnCom);
    DataModule1.zqInsertXML.ParamByName('pvProd').AsString := Trcpv(vProd);
    DataModule1.zqInsertXML.ParamByName('pchval').AsString := cnpj+fone;
    DataModule1.zqInsertXML.ExecSQL;

    xmlNCab := xmlNCab.NextSibling;
end;

This code above is only a small continuation of the answer to this earlier question: Access Violation When Selecting XML File - NFe

And I believe that the error is in this while, because it selects items from my xml, but when it has only one item, it selects more than necessary, that is, it adds some empty items.

Here's what happened:

Any ideas?

Eventually I found out by myself.

Follow the code:

// Leitura Dados Itens da Nota Fiscal...
  // Aqui eu peço para encontrar a primeira ocorrencia da Tag <det>>
  xmlNCab := NoPrinc.ChildNodes.FindNode('det');
  // Posiciona o primeiro elemento encontrado
  xmlNCab.ChildNodes.First;
  repeat
    // referencia a tag <prod> dentro de <det>
    xmlNItm := xmlNCab.ChildNodes['prod'];
    xmlNItm.ChildNodes.First;

    inc(l);
    sgProds.RowCount := l;

    repeat
      if xmlNItm.ChildNodes['xProd'].text <> ''
      then
      begin
        cProd := xmlNItm.ChildNodes['cProd'  ].Text; // Código do produto CFOP
        xProd := xmlNItm.ChildNodes['xProd'  ].Text; // Nome do produto
        uCom := xmlNItm.ChildNodes['uCom'    ].Text; // Sigla unidade da embalagem
        qCom := xmlNItm.ChildNodes['qCom'    ].Text; // Quantidade do produto (4dec,S/M)
        vUnCom := xmlNItm.ChildNodes['vUnCom'].Text; // Valor unitário do produto (4dec,S/M)
        vProd := xmlNItm.ChildNodes['vProd'  ].Text; // Valor total do produto (
        //2dec,S/M)

        sgProds.Cells[0,l] := cProd;
        sgProds.Cells[1,l] := xProd;
        sgProds.Cells[2,l] := uCom;
        sgProds.Cells[3,l] := qCom;
        sgProds.Cells[4,l] := vUnCom;
        sgProds.Cells[5,l] := vProd;

        DataModule1.zqInsertXML.Close;
        DataModule1.zqInsertXML.SQL.Clear;
        DataModule1.zqInsertXML.SQL.Add('INSERT INTO xmlprod(cProd, xProd, uCom, qCom, ' +
          'vUnCom, vProd, chval)');
        DataModule1.zqInsertXML.SQL.Add('VALUES (:pcProd, :pxProd, :puCom, :pqCom, ' +
          ':pvUnCom, :pvProd, :pchval)');
        DataModule1.zqInsertXML.ParamByName('pcProd').AsString := cProd;
        DataModule1.zqInsertXML.ParamByName('pxProd').AsString := xProd;
        DataModule1.zqInsertXML.ParamByName('puCom').AsString := uCom;
        DataModule1.zqInsertXML.ParamByName('pqCom').AsString := qCom;
        DataModule1.zqInsertXML.ParamByName('pvUnCom').AsString := Trcpv(vUnCom);
        DataModule1.zqInsertXML.ParamByName('pvProd').AsString := Trcpv(vProd);
        DataModule1.zqInsertXML.ParamByName('pchval').AsString := cnpj+fone;
        DataModule1.zqInsertXML.ExecSQL;
      end;

      xmlNItm := xmlNItm.NextSibling;
    until xmlNItm = nil;
    xmlNCab := xmlNCab.NextSibling;
  until xmlNCab = nil;
