Yet Another TCX Parser
yatsx_parser in a more advanced parser of the Garmin data files that was influenced by python-tcxparser.
The main difference from the rest of the available parser is in the core idea of the project that is connected to the OpenLAPP framework (to be published) that requires interaction with a more low-lever data with more advanced data aggregations.
Current version extracts the following properties:

• features dictionary of the available features in the .tcx file
• has_powers flag that shows availability of the power measurements in the files
• powers list of the extracted power measurements
• grades list of the extracted slope grades in degrees
• distances list of the passed distance
• moves list of the moves during a single measurement
• low_altitude_distance passed distance on a low-altitude (by default, 1500m)
• high_altitude_distance passed distance on a high-altitudee (by default, 1500m)
• elevations list of the elevations
• total_elevation total elevation (or some of the positive climbs)
• heart_rate list of the heart rate measurements
• mean_heart_rate average heart rate during the session
• speeds list of the speeds
• altitudes list of the altitudes
• cadences list of the cadences
• high_altitude_time total time on the high-altitude(by default, 1500m)
• total_distance total distance passed during the session
• calories total calories
• total_time total session time
• datetime session start time
• date session date
• get_path(path, namespace) Read a value of a random value that could be found in the path inside of the namespace
• read_xpath_property(xpath_obj, name)Read a numeric property name in the given xpath_obj object

Default namespaces from Garmin

file_name mandatory parameter with a path to the .tcx file
pre_read flag that makes a pre-initiation of the data for a quicker access if the same properties are expected to be called many times. Default: False
params dictionary of parameters
recovery flag to perform data recovery with a linear interpolation. Alternatively set by the params. Default: True

By default, the parameters are set as following:

default_params = {  
    'high_altitude': 1500,  
    'recovery': True  
}

That corresopnds to a default min altitude of 1500 meters and replace all the missing values with a linear interplation model.

filename = '1.tcx'
tcxparser = TcxParser(filename, pre_read=True)
tcxparser.powers  
# get list of the powers [0,0 ... , 0, 0]  

'+' confirmed compatibility
