I intend to enter values from a list at each step. Including the zeros must remain. "1" must be "01":

values={{01,03,05},{08,09,10},{07,08,15}}

ToString["  <valores="#" dataCriacao=\"24/11/2016\" grupo=\"Grupo1\">
   <conc=\"-1\" dataAssociacao=\"01/12/2016\" />
 </LMC>"] & /@ values

How should I proceed?

This is the result I want to get:
