Importing XML files into Excel

I have a number of XML files returned from a survey created with Adobe Acrobat Professional and have not determined how to get multiple files into separate rows in an Excel 2007 spreadsheet. Each file is identical, only 7 fields (responses) to the survey. All efforts only allow me to import one of the files, with no appending. Each file imported overwrites the previous file's data, even if "append new data to existingXML tables" is checked in XML Map Properties. I know I'm missing something very basic here and could use some guidance.
