XML for path query to T-SQL query - sql

Question

I have a pretty complex query that uses the 'XML for path' to return an XML. Now I need this query as a regular T-SQL query, but I have great difficulty converting this. I have searched for a tool or another topic that can convert this or give more information how to easily transform this query to a regular t-sql query. Any help would be greatly appreciated!
