SQL XML :: Adding Node To XML Field If Not Exist To Validate With Schema

I have following data in my table. In some of the elements there can be missing nodes. I need to find out missing nodes from each element and insert default node if it doesnt exist so it validates with schena.from below exmaple in the third element location node is missing and i would like to add default node if we see any of these.

Input
CREATE
TABLE #t (xmlfile
XML)
INSERT 
INTO #t
       
[code]....

Some times Location tag name can be Location10. like <Location10>NY</Location10>.In this case i need to update <Location10> to <Location> to validate with XML schema.
