A script for making the XML exports from the iOS Health app more human-friendly
#!/usr/bin/env python
"""
A quick script for tidying up data from the HealthKit export file.
To get an export file:
1) Open the Health app on iOS
2) Under "Health Data", select "All"
3) Use the share button to get a copy of your data in XML format
This script allows you to get data for one particular value, and turn it into
a slightly more human-readable form.
Use `get_available_types()` to get a list of all the `type` keys used in the
XML data. Find the one you want, and then pass that into
`get_values_for_type()`. I'm assuming that the data is an integer; if that's
not correct, change lines 48 and 55.
The `main()` function has an example for getting step count data.
