How to parse cue-sheets from bikeroutetoaster (in order to prepare an aid-station summary)
Consider this, you are using http://www.bikeroutetoaster.com/ (brt) to create a running course where you want to provide aid stations. In brt you do this by adding course-points (other points are track-points). When you add a new course-point or convert any existing track-point to a course-point you are asked to give it a name, type, and directions (or general description). For aid stations set type to Food.brt then generates xml code which you can download on the cuesheet page. The xml looks something like this:
...
<point>
<lat>48.614215</lat>
<lng>8.967376</lng>
<legDistance>5.57</legDistance>
<totalDistance>26.26</totalDistance>
<height>522</height>
<pointType>Food</pointType>
<name>VP1</name>
<directions>Parkplatz Kohltor (Hildrizhausen)</directions>
</point>
<point>
<lat>48.60916</lat>
<lng>8.96905</lng>
<legDistance>0.58</legDistance>
<totalDistance>26.83</totalDistance>
<height>517</height>
<pointType>Right</pointType>
<name />
<directions />
</point>
...
So what I wanted from this was a listing that shows all points marked as Food (aid stations), at which mile/kilometer they are reached and the delta distance. In addition I output transit times for aid stations given estimated min/max finisher times. This gives some idea how long each aid station should be available.
The perl code to do this is printed here (download link below).
To run this script just provide the xml cuesheet filename as an argument on the commandline. $min_h and $max_h specify the expected minimum and maximum finisher times in hours.
