I'd probably write something in python to work directly on the gpx file. There are decent libraries for working with xml. An easier approach if you don't code (much) is to use gpsbabel to convert to a csv file then your favourite spreadsheet. Then possibly gpsbabel again to get back to gpx depending on your analysis.

The edit probably won't have to change the data point timestamp but may have to do something about elapsed time. I think that's a separate field, from memory.

Have a look at gis.stackexchange for gpx hacking advice.
