The user is trying to get spectral library information out of Sciex software, which is currently more or less impossible. Apparently Sciex plans to add a text-based export in .SDF format, which looks like yet another "standard" along the lines of .msp where more or less anything goes. An example file is provided in the support thread mentioned above.

Some useful notes on .SDF can be found here:
