Hi Sebastien,
You can show additional XML fields by adding them to the parser configuration. For example, in the scenario above, you could modify your parser configuration by adding:
<log4j:data name="EquipAddress" value="%S{EquipAddress}"
The %S field definition will extract the contents of the string to a new "EquipAddress" column. Note that each field definition will result in a new column, so it is best to limit the total number of definitions.
You can find out more about the %S specifier here:

Hope that helps,
Toby
