Converte um mapfile em um arquivo XML

O padr&atilde;o XML utilizado &eacute; compat&iacute;vel com a estrutura de um projeto do softwrae GVSIG ate a vers&atilde;o 1.1
Esse XML &eacute; utilizado pelo plugin do i3Geo para GVSIG, que permite visualizar a &aacute;rvore de temas do i3Geo dentro do GVSIG.

No caso de layers que fazem acesso a banco de dados, a string de conexao e bloqueada por default

Para desbloquear e necessario editar a variavel de configuracao existente nesse mesmo arquivo
