How to find out All tables names & columns list use by SSRS Report

I have 600 SSRS reports deployed into production. How can I get meta data information of reports? Things like which reports use which tables. If any reports use more than 1 table, I am trying to get all tables used by the report.

Is it possible to get such info? Please help me

I had to change the 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' bit to the appropriate year your SSRS is, otherwise you get 0 rows in results.
