Tipos de Arquivos XML

O Host On-Demand e o Database On-Demand suportam dois tipos de arquivo XML:

O Formato de um Arquivo XML DTD

Um arquivo XML DTD contém:

A finalidade da DTD (Document Type Definition) DatabaseOnDemand é permitir que os programas leiam arquivos XML (como por exemplo editores XML) para validar o conteúdo do arquivo XML em oposição à DTD. A DTD DatabaseOnDemand é definida da seguinte maneira: 

<!DOCTYPE DatabaseOnDemand [
<!ELEMENT DatabaseOnDemand (QUERY)>
<!ELEMENT QUERY (ROW+)>
<!ELEMENT ROW (COLUMN+)>
<!ELEMENT COLUMN (#PCDATA)>
<!ATTLIST COLUMN NAME CDATA #REQUIRED>
<!ATTLIST COLUMN VALUE CDATA #REQUIRED>
]>

O texto a seguir mostra alguns dados XML de amostra criados de acordo com a DTD DatabaseOnDemand: 

<DatabaseOnDemand>
  <QUERY>
    <ROW>
      <COLUMN NAME="TOPICID" VALUE="9" />
      <COLUMN NAME="EXAMPLID" VALUE="54" />
      <COLUMN NAME="DESCRIPT" VALUE="Vendas do Funcionário" />
      <COLUMN NAME="OBJECTID" VALUE="19" />
    </ROW>
    <ROW>
      <COLUMN NAME="TOPICID"  VALUE="12" />
      <COLUMN NAME="EXAMPLID"  VALUE="74" />
      <COLUMN NAME="DESCRIPT"  VALUE="Total de Vendas" />
      <COLUMN NAME="OBJECTID"  VALUE="22" />
    </ROW>
   </QUERY>
</DatabaseOnDemand>
No exemplo acima, TOPICID, EXAMPLID, DESCRIPT e OBJECTID são os nomes de colunas a partir do banco de dados do host.

O Formato de um Arquivo XML Excel

O arquivo XML Excel pode ser aberto e modificado pelo Microsoft Excel 2003.

A seguir encontra-se uma amostra de um arquivo XML Excel:
