List Expressions and Values of Variables in SSIS package

,

1 - Locate the target packages (this works as scripted on the raw dtsx files)

2 - copy the script to an SSMS query window

3 - Place the full path to the first such package in the script (it's in the SourcePackage CTE)

4 - Execute.

5 - Save results in whatever form you wish

6 - repeat steps 3-5 for each package you wish to document.

-- I've limited it to the Variables collection but the world's your oyster with XML - just adjust the Cross Apply nodes to get at other stuff.
