You can do the following:
(1) Open the script in Inquisit Lab, then parse it (click the "Validate script" button).
(2) Click on the "Output" tab at the bottom:
There you'll find parsing result, which is a list of all the elements in the script, in the order they were parsed. The output can be selected and copied:
(3) Then you can paste the output into a text editor of your choosing, and you'll have your list of elements (example attached).
Alternatively or in addition, since Inquisit script files (*.iqx) are simple text files (not some binary format), you can use a simple diff tool (e.g. WinMerge under Windows; http://winmerge.org/
) to compare the two (complex) scripts -- this will highlight any differences.
