Extract connectionstring details from a SSIS package

Hi,

Want to extract the connection string details from SSIS package which is saved in a file system.

I have done it some years back using the below link 

https://social.technet.microsoft.com/wiki/contents/articles/25150.t-sql-retrieve-connectionstring-details-from-a-ssis-package.aspx

But now, seems like this is not working. May be we have to change the query or xml tags.

The XML code of the package is as shared in below link

NOTE : I am using Visual Studio 2015 and SQL 2017.

Thanks in advance.
