how to change weapon to use with skill level and not with a level

[7875112]

I wonder how I can change the weapons for the player needs to use a skill
and not a level

example
change <melee id="2392" Level="40" unproperly="1" event="function" value="default"/>
to <melee id="2392" Sword="40" unproperly="1" event="function" value="default"/>

Thank you very much
